Ultimate Foundation Crochet Stitch Class!

My review of an important crochet class taught online by Marty Miller


It turns out that the most popular post of this blog is "Which Foundation Stitch? And Why?" If you were reading that post just now, then you're probably here because you want to learn even more about foundation stitches. I can't imagine a better way than to take this class—no matter how much crochet experience you have.


Doesn't this look like fun?
Marty Miller created an online seven-lesson class on foundation crochet stitches. Craftsy produced it. If you've already taken a Craftsy class, you know that you can interact with the instructor and view it at your own pace multiple times. You can also leave bookmarks and notes to yourself along the way, and download class materials.


I learned a lot from Marty's class, even though I already use foundation stitches in my crochet. While taking this class I was also in the midst of comparing methods for extreme increasing in Tunisian crochet lace. (See the resulting newsletter issue #64.) 
Test of 3 different end increases for
Warm Aeroette Tunisian Filet Scarf.
See this DesigningVashti stitch how-to.

Increasing whole groups of lacy Tunisian stitches at the end of a forward pass can be a tricky, tricky thing. (I often do this for Tunisian filet designs.) To add an infinite number of stitches this way, what you really need to do is add foundation stitches. Specifically, lacy ones. It takes a bit of engineering and I just hadn't thought of it this way at first.

stitches added to both edges. (Part of a
stitch how-to for Warm Aeroette.
Marty's class is mostly about regular crochet, but it can be applied to other kinds of crochet too. One of the valuable things Marty does in her class is explain how to make a lacy foundation row that's based on a lacy stitch pattern.

Mastering Foundation Crochet Stitches is full of Marty's original material, distilled from her years of teaching classes on foundation stitches, *plus* her class on extended stitches too! In fact, Marty teaches how to crochet extended stitches in Lesson One. It's an ingenious move to use extended stitches as a way to introduce foundation stitches.

She has a patient, step by step teaching style, and speaks with a calming, knowledgeable voice. Her personality, teaching skills, crochet love, and special tips show. 

Marty's Craftsy class is a bargain. Turns out Tammy came to the same conclusion! Have a look at Tammy Hildebrand's review, swatch, and description of each lesson.

Blocking Crochet: Five Methods

I recently updated this post and created a permanent page for it at my new website!

One of the methods below could be the perfect finishing touch for your next crochet project, depending on your yarn and project type. It also depends on your own preferences. Each crocheter has a favorite method.

Special considerations for a specific stitch, technique, or project follow.

Five Crochet Blocking Methods

This is how love knots crocheted in wire look at first.

 Listed from the least aggressive to most.
Same love knots, "dry blocked(method #1; 
I used the crochet hook to help open them up)

Dry Block

A.k.a. hand iron. Every crocheter has done this without even knowing that it has a name. Stretch, spread out, and flatten your crochet piece on something flat. 

One's knee always seems to be nearby! Using one's knee or upper leg is not too bad for a small item, especially if you're wearing jeans or other fabric that provides a bit of friction. (Don't use it for measuring a gauge swatch though!) 

If your surface is hard and flat, such as a table, you can also press it, i.e. "hand-iron" it. 

Personally I almost never use this method.

Damp Block

A.k.a. spray block, and block with mist. Spritz liberally with water, especially the edges, then spread out on a toweled surface to dry. It's ideal for a quick block as you crochet every 8 inches or so of rows. Especially if you use yarns that respond dramatically to it like I tend to do, such as those with at least 20% rayon/viscose/tencel content.

This method is my personal favorite. I blogged about it back in 2010. I also combine it with methods 3 or 4 below: damp block while crocheting, then a final wet block when the project is completed. I prefer damp blocking partly because it's the most portable, and partly because it's fast. For most of the year here in humid Florida, wet things take too long to dry! 

Use a bath towel on a flat surface; the towel will provide some friction that I find in most cases replaces the need for pins.


Wet Block

Fully immerse it in water. This is Doris' favorite methodYou can soak plant fibers like cotton, linen, hemp, rayon in warm or cool water a bit. 

For non-superwash wools, immerse briefly in cool water to avoid fulling (felting), then remove excess water gently before spreading out on a toweled surface to dry. ShamWow super absorbent microfiber cloths help to speed up the drying here in humid Florida. I use them instead of/on top of a bath towel on a table.

I like to add a little hair conditioner to the water if the yarn is wool or silk. 


Steam Block 

When it comes to crocheting clothing with drape, I'm looking at you, acrylic yarns. Blocking with steam is an aggressive method, so you must first carefully test, each time. 

It can really pay off! It gives some acrylic yarns the beautiful sheen and drape of silk

Using steam blocking is an art that can bring out extra softness and luster in some silk, camel, and llama fibers too. More on this below.


Pin It, or Stretch on Blocking Wires

This is the most aggressive blocking method and so there is an art to doing it the optimal way. (You don't want to block a stretched, stringy, stressed appearance into the yarn or stitches, or leave permanent dents in stitches from the pins.) It's combined with wet blocking.

Personally and non-professionally, I have only ever pinned crocheted snowflakes. I usually see this method used for afghan squares before seaming them together, and for knitted lace. 

Perhaps the most important thing of all is to use rust proof pins! I don't own blocking wires, but I sure admire the knitted lace wraps that have been blocked with them.


Special Blocking Considerations


Blocking is actually an art, and you might enjoy this newsletter issue about that. 

Picots 

Tug and pinch each picot to round it out and make it visible, adding more water to them than the rest of the stitches, if necessary. 

Love Knots

Most love knots are intended to be plump, like a semi-inflated balloon. If yours are, damp block them. Spritz lightly with mist and smooth gently in a way that doesn't flatten the love knots, nor weigh them down with too much water. You might feel like it's not worth blocking them at all, but I tested this in my love knot classes and people could tell the difference.
UNBLOCKED Tunisian filet-style leaning crochet swatches

Yarn Color Issues

If the yarns you used might give off some excess dye, avoid wet blocking. Use light spray blocking instead. Maybe combine light mist with heavy #1 and/or #5.

Special Laces  

WET BLOCKED to remove biasing. (method #3.)
Tunisian crochet lace and filet crochet respond great to wet blocking (also very careful steam blocking if you used acrylic yarn). 

Aim for squared filet eyelets. 

For Tunisian crochet lace specifically: tug on the return pass lines to straighten evenly. Tug vertically more gently. On extended Tunisian stitches to fully extend them, if you used them, you must tug on them vertically to open them up. 

Garments

Wet blocking is the method here for a stylish fit, silhouette, and an elegantly flowing, breezy movement. See Doris Chan's blog post. If you used acrylic yarn, steam blocking can bring out fashion drape and gleam as if you used silk! 

Be sure to block the accessories that need to drape stylishly, such as wraps, scarves, collars, and even necklaces. 

Tip!: Steaming some animal fibers will soften them enough to wear around the neck. This came in handy for a men's scarf I crocheted in a yarn that had camel hair content!

Home Decor

Especially doilies, snowflakes, and afghan squares; also flowers and other appliques: These are the projects I have the least amount of experience blocking by any method. The most notable thing about them is that they usually need to be as perfectly flat and square, or round, as possible. Wet blocking with pins or wires is common. Sometimes starch is added (especially for snowflakes). 

And finally...for all blocked items by all methods:

Let air dry completely, then admire your work and bask in the compliments! And remember: the best time to take photos of your work is right after it's blocked.

Crocheting Into Love Knots: Special Tweaks

This is the third and last post of a three-day series about crocheting Love Knots (a.k.a. Solomon's Knot, Lover's Knots, or Knot Stitch). The earlier two posts are: 
- How to Crochet a Love Knot (See the freshly updated version of this post.)
- Three Ways to Crochet Into Love Knots.
This mini-series presumes that you already know how to make a slip knot, and how to crochet chain stitches and single crochets (UK: double crochet). To learn how to crochet a Love Knot, see the first post in this series (above). The abbreviation "sc" means single crochet stitch in the US; in the UK it's "dc."

-:-------:-

Today's post is about two small stitch modifications ("tweaks") that bring out the best in one's Love Knots. I use these the most to keep a Love Knot from loosening up over time. Several things can cause the stitch to do this: the yarn type, a loose gauge, and the weight of the rest of the stitches pulling on each other. Also, the weight of beads, if you use them.

Tweaks abound in crochet and that's something I love about it! Tweaks are what get shared at crochet conferences and you're lucky to be there when they surface. To me, our real crochet culture is in these unofficial, off-road modifications crocheters are actually doing.

If you have your own favorite Love Knot tweak, please share it in the comments.


I. Lock It Down With a Tight Chain Stitch

Zuma Skirt by Doris Chan
Photo © 2013 Interweave Press.
Here's how: You've made a long loose chain, then knotted it with a sc to complete your Love Knot (see Part 1 for a refresher). Now chain 1 tightly. You can even yank it tight. You've added a padlock to that knotted love, baby.

It's easy, fast, and it seems to melt away from view. I've not found it to change drape or stretch. I do not crochet into it in the next row. I just ignore it.


Sweetberry Clasped Love
This was Doris' strategy of choice when she designed the Zuma skirt (shown at left). Skirts need to be able to hold up to real wear, and Doris didn't want the Love Knots loosening and looking sloppy over time.

It was a crucial tweak for me when I used metallic embroidery floss and beads for Sweetberry (shown at right). That floss was so slippery and wiry that it would start uncrocheting itself as soon as I finished each stitch! Not only that, the weight of the beads encouraged this misbehavior and just looked like a mess. A yanked-tight chain stitch fixed this.



II. Compress the Sc Knot

This tweak is so important to me that it's what caused me to do this three-part series. It's difficult to describe in patterns, so I created a photo tutorial for it, and then I wanted to share it!

Basically, when you crochet into the sc of a Love Knot, crochet into three loops of the sc, not just two. But which three?
The yellow-tinted loop is the 3rd loop that I use to compress the knot.
You can see with the gold needle on the left that it has all three loops on it.
If I don't do this, that's the loop that tends to loosen and drop down.

So while you're crocheting the next row, the backs of the sc you crochet into will be facing you. Insert your hook into the top two loops as usual, and tilt the top of the stitch toward you and down a bit to see that third loop at the bottom of the sc (as shown in the photo).

Compare these two images, one with the tweak, the other without it:
With the tweak (3 sc loops crocheted into, not just 2).
Note that the backs of Love Knots are facing.
Standard way, NO tweak: I crocheted into only the top two
loops of the sc. See how the Love Knot loosens? Look at how
the whole row looks uneven and sloppy. The loop that has
dropped down the most is the 3rd one I use in my tweak.  
Note that I tugged on all stitches to simulate wear, and used a looser gauge to help make all loops more visible.

That helpful third loop is actually one of the side loops of a sc, sometimes called one of its "legs" or part of its "post" or "stem." It's the same side strand that is used when making a popular type of picot
Beach day for the Electra Wrap.

When it comes to Love Knots, however, familiar loops look unfamiliar, and shift around. The side loop of the sc looks like a bottom loop instead when it's part of a Love Knot. This is one of those things about Love Knots that confuses folks! 

Now you know my special tweak for preserving the Electra Wrap's starry charm.

Three Ways to Crochet Into Love Knots (a.k.a. Solomons Knot, Lover's Knot)

This is the second of a three-day series about crocheting Love Knots (a.k.a. Solomon's Knot, Lover's Knots, or Knot Stitch). This mini-series presumes that you already know how to make a slip knot, and how to crochet chain stitches and single crochets (UK: double crochet).

Yesterday's post was about crocheting a single string of Love Knots. Depending on your project, it might be called "the foundation row" or "Row One" or, "Hey look, I just made a necklace/eyeglass cord/wrap bracelet/ tie belt!"

Free Love Knot pattern

Things get really interesting when we crochet Love Knots (and other stitches) into Love Knots. Not only do we have fun choices, Love Knots can mess with your mind. Seriously.

A single string of Love Knots is three-dimensional, like a sculpture of bubbles. Crocheters often lose their way when it's time to turn and begin a new row. The risk of accidents (changing the stitch count, adding a twist in the foundation row) can make even a seasoned crocheter twitchy about this stitch.


The first step is to know when your Love Knot is upside down! Let's dissect the loopiness.



Anatomy of a Love Knot


Doesn't the bottom of the single crochet
look weird when it's facing up?
A common mistake is crocheting into upside-down Love Knots when you don't mean to. The top loops of a Love Knot can look weird. The easiest way to identify them is to look for the top two long loops (tinted green), which are always paired. In contrast, the bottom long loop of the Love Knot (tinted yellow, above) is always a singleton.

The top two loops of the single crochet (sc) have more of the familiar chain-link look, like the top two loops almost all crochet stitches have (tinted pink, above).


Unless a crochet pattern states otherwise, plan to crochet your next row into both top loops of either the sc (pink) or the long loops (green).



The Three Ways to Crochet Into Love Knots


Method 1.

The most common nowadays is to single crochet (sc) into the sc "knot" part. (I say "nowadays" because old thread crochet patterns often used the second method, below.)
Insert your hook under the pink loop AND
the other top loop behind it (not showing in this photo.)
An example of sc stitches
crocheted into the sc of Love Knots
(Sister Act Shawl).

This is the method I used for the "Sister Act Shawl and Shrug" published in Interweave Crochet magazine, Summer 2013 issue.

Fish Lips Lace.

Less common variations: You can crochet a different stitch into the Love Knot sc, for example double crochets (dc; UK: tr). That's what I did for the Fish Lips Shrug

When you crochet taller stitches into the Love Knot sc's, special things happens. The Love Knots have more room to expand. I find that Love Knots have a special affinity for dc stitches in terms of scale.



Method 2.

Single crochet before and after the sc "knot." This means one sc into two long top strands of one Love Knot just before the next sc "knot," and a second sc into two long top strands of the next Love Knot just after the sc "knot." 

This traditional method has several merits. It makes even the finest thread easy to crochet with, because the long loops are very easy to see and crochet into with a tiny, tiny crochet hook. It reinforces the places where the rows are linked to each other. The weight-bearing stress is distributed across more threads and stitches. This helps even the largest, most delicate lace pattern support its own weight, with less wear - while also holding open the lacy part of each Love Knot!
Method 2: Emphasis on the knots.

It does take a bit of foresight when planning the foundation row because you'll be adding more stitches in the next row (another sc each time you crochet into the Love Knots). Another factor to consider is that the extra sc can make the knot parts look lumpier in thicker yarns.

Variations: I hope you feel free to try this with other stitches besides a sc, such as the half double (hdc; UK: htr). Crocheters did 100 years ago!


Method 3. 

This is the rarest of the three: crochet into the long strands of only one Love Knot (not two, like in Method 2). In the inset photo below you can see a resulting stitch pattern. In the top two long loop of each Love Knot I crocheted a sc and a Love Knot.

This Marisa Artwalk (in progress) is a free form type of Love Knot pattern. Part of its unusual look is due to using Method 3.

How to Crochet a Love Knot, Part 1 of 3

Nov. 2017 UPDATE: I revised this post and created a permanent page for it my new website. After that one see its new companion, "Crocheting the Love Knot Mesh".

This is the first of a three-day series about crocheting Love Knots (a.k.a. Solomon's Knot, Lover's Knots, or Knot Stitch). This mini-series presumes that you already know how to make a slip knot, and how to crochet chain stitches and single crochets (UK: double crochet). 
Today is about how to crochet one stitch. One Love Knot at a time. Topics of the other two posts in this miniseries are: 
- Three Ways to Crochet Into Love Knots.
- Crocheting Into Love Knots: Special Tweaks.
 

The Foundation Love Knot

A beautiful, beautiful thing about Love Knots is that you don't need to start with foundation chains. Love Knots can easily serve as their own foundation row.

A foundation row of Love Knots of equal size. This is the front.

As students exclaim in Love Knot classes, "You mean I just make them in the air?" YES. Like magic (or like the chain stitch), you just crochet Love Knots out of thin air.


Step 1, The Loose Chain Stitch 

Use a smooth, light-colored yarn and a crochet hook size that goes with the yarn. Make a slip knot and place a loose loop on your hook. 'Loose' means about an inch long. Now yarn over and pull the yarn through to make a loose chain. 

If you know how to crochet a chain, this is nothing new. Feel free to crochet a few chains first, even tight ones if you like.
Notice loop "A." That's the important 
one for Love Knots.

Know Your ABCs!

Compare the three loops of your loose chain to the A, B, and C loops in the drawing at right. 

Love Knots have a reputation for being tricky. Feeling unsure about which loop of the chain stitch to use is a common hurdle. 
Now you're ready for Step 2.


Step 2, Tie the Knot in That Love with a Single Crochet

The single crochet stitch in progress. 
(Ignore the label "D" which is for 
beading purposes.)
Single crochet in loop A. Insert your hook between Loop A and the other two loops, yarn over (as shown in the next drawing), pull through the loop: 2 loops on your hook. Yarn over and pull through both loops on your hook to complete a normal single crochet.

That's it, you're done, you created a Love Knot out of thin air!


Step 3, One Love Knot, Now What?



Lovebud Vine Charms

Love Knots!
Sparkle Love Knot Lariat
You have one loop on your hook after completing the single crochet. You can now launch right into a second Love Knot, as shown in the photos at the top of the post. 


-:-------:-

Since we're crocheting, there are of course lots of fun Love Knot variations. For example, instead of a single crochet in loop A ("the bump loop") of the chain, try a different stitch, or group of stitches. Instead of loop A, try crocheting into a different loop or loops of the chain. Once you're clear on how to make a classic Love Knot, invent your own variations. Try a wide range of yarns, too - the same Love Knot can look very different in other yarns.

How to Crochet Into that Third Loop or Lower Horizontal Bar of Single Crochets

The moral of the story is, if you think you're looking
at the tops of stitches, you probably are
. Orbit Cowl
The third loop is required for "camel crochet." It has also been called the humpbump, nublower loop, back-back loop, and lower horizontal bar of the single crochet (sc in the US; double crochet or dc in the UK and Australia). The patterns that result from using this loop in different ways have been called Savvy Single Crochet, and Camel Crochet™. 



Pallas Scarf uses a few kinds of third loop
stitches. Its prominent top loops give this
design a strong impact.
I've listed these alternate names first so that crocheters searching for help have a chance of finding this post! For some reason this loop - a simple part of a simple stitch - is ignored in the crochet how-to books. (Be sure to see the end of this post for a chronological list of books that mention this topic somehow, and some how-to videos!)

It's not that I think beginners need to launch right into using it, but if it were named in a diagram along with other stitchy bits, it would give newbies a stronger foundation for broadening their understanding later. We'd have a common language. Designers wouldn't think twice before using it.

Here's how to find the loop in sc and use it. (Scroll down for hdc.) I've used it in a few of my patterns and want to use it more without confusing people. 
Single crochet stitches. This is a close up of the next photo below. I tinted the third
horizontal loop of the single crochets. The copper needle point is inserted through the
loop from under it, just like you'd do with the crochet hook for a nice ribbed look.

1. Loosely crochet a row of some sc. You already know about the two top loops of a sc, right? They're the ones you crochet the next row of stitches into (unless directed otherwise). The top loop nearest to you is the front loop and the other is the back loop. These loops are labeled consistently in the books.

2. While you're crocheting each sc, you see the front of it. Look closely at how different the back is from the front of the stitch. The main difference is a small horizontal bump strand on the back only, just under the top loop.
The fronts of the dark blue rows are facing us, and their top loops are bent over toward us, because the light blue rows were crocheted into this third loops. We're looking at the tops of their heads.
I crocheted the dark blue rows into both top loops of the light blue sc.

Issue #61 of Crochet
Inspirations Newsletter
Not only can you crochet into that third lower bump loop, you shouldFor more on the uses and possibilities of this third loop, please see issue #61, "Top Loops Optional," of Vashti's Crochet Inspirations Newsletter.

3. Finish your first row, chain 1, turn. Now the backs of the first row stitches are facing you. Look again for the third horizontal loop of the stitches. Skip the first sc and insert your crochet hook in the third loop of the next sc, from under the loop (not down through the top), then yarn over and pull through the loop. You should have two loops on your hook. Yarn over again and pull through both loops to complete a sc. 
Ever wondered if third loops are used
for the Thirsty Twists Bathmat?
Yes, but not as many as you think.


Three Tips!

It's weird and slow to crochet into this loop at first, but like everything, it gets easier. (I've only used the stitch in small strategic areas of my designs for effect.)

1. Keep stitches loose; use a larger crochet hook.

2. Use a pointy-headed crochet hook. You can even file the head of some of them to customize it.

3. Try this: when you pull up a loop in that third loop and leave it on your hook, pull up on it a bit. I've seen some people make their sc with their hook at an angle - angled toward the beginning of the row (held more horizontally than vertically). This makes a slightly stretched, taller sc with a loosened third loop, making it easier to crochet into.

The key to the effect is that none of the top loops of the first row are covered by stitches in the next row, so they ride along the surface as a neat chained-looking ridge.


Now for the Half Double Crochet (Hdc)
I hear some of you saying, "I do this already with hdc to make a squishy hdc ribbing!" And crocheting into the third loop of hdc is more common (though not as common as you'd think, if the crochet stitch guides are any indication). It's also easier because the third loop of hdc is looser.
These are all hdc. I color-coded the two different kinds of "third loops."
The only one I've used in designs, and have seen others use, is tinted pink.
The lemon-tinted one is worth trying, though. It makes a rib that's less offset
and bent. It's structurally the same as the sc third loop.
Interestingly, that hdc third loop is anatomically different from the sc third loop. (See newsletter #61 about this.) 

I checked about 30 likely books for any explanation of this third loop of sc and/or hdc. Here's a chronological list of the what I turned up.
