A Study of Pooling in a Variegated Sock Yarn

Several days ago, I decided to knit a pair of plain vanilla socks using Serenity Sock Weight Yarn (Premier Yarns) in the colorway Amethyst. This was a yarn I had purchased at my local Hobby Lobby and had been sitting in my sock yarn stash for a few months. In the skein, the yarn appears to be a mix of greys and purples, and I thought it would result in a striping of the socks. The label does not indicate that the yarn is “self-striping”, but the picture on the label shows a sock with an interesting variation of stripes.

Since I had never knit with this yarn, I knit a circular swatch to determine needle size and gauge before starting on my socks – and this is where my study in “Pooling” began. I started with US 2 (2.75 mm) needles and cast on 64 stitches (which is what I would use for my socks with a gauge of 7 stitches per inch). As I worked on the swatch, I noticed that the yarn was not knitting up in the stripes the way I had anticipated – in fact, it seemed to be predominately purple on one side of the swatch and predominately grey on the other side.

Obviously, I had some “pooling “ going on. Pooling is an effect that occurs when a variegated yarn knits up in “pools” of color, rather than in stripes. Now, I wasn’t really sure I liked the effect – and my stitch gauge was 6.25 spi, rather than the 7 spi I wanted.

So, I decided to do a second swatch with fewer stitches, a smaller needle – and because I had read about pooling in a Rav thread, I also decided to knit from the outside of the skein instead of the inside. I cast on 52 stitches on size US 1.5 (2.50 mm) needles and knit away – and I got more striping – not even stripes, but definitely stripes on both sides of the swatch.

So, I took a picture of the two swatches and posted a comment on Ravlery under the thread, “Examples of Pooling Good & Bad”, stating what I had observed along with my assumption that the change was probably due to knitting from the outside of the skein – and completely ignoring the fact that I had changed the number of stitches in the swatch and this might also be contributing to the way the colors were knitting up.

I must admit, I did not anticipate much of a response to my comment in this thread. But I received several. It’s one of the things I love about Ravelry – fellow knitters are always willing to share and question things. Anyway – after reading the comments, I decided I needed to do a little more work before I could actually answer my fellow Ravelers’ questions.

Off I went to swatch again – this time I decided to start from the inside of the skein, use US 2 (2.75 mm) needles and begin by casting on 72 stitches. I knit approximately 1.5 inches, then purled and decreased the number of stitches to 64 stitches, knit another 1.5 inches, purled and decreased to 54 stitches and knit another 1.5 inches. Here’s a picture showing how the yarn pooled with different numbers of stitches.

So – in response to Robocass and Hypercycloid, who asked me if the difference might be due more to the difference in the number of stitches in my swatches: Clearly, the number of stitches used results in very different color patterning and it doesn’t really matter whether I knit from the inside or the outside of the skein.

Hypercycloid also asked about the length of each of the colors in the yarn. Hmm – I hadn’t thought about that, so I got out the measuring tape and discovered that each purple section of the yarn was approximately 19 inches, while the grey sections were approximately 12 inches. Not quite, but almost a 3 to 2 ratio. Statnerd suggested I count the number of grey stitches compared to the purple stitches in my wider swatch – I did and ended up with 27 stitches of grey to 37 stitches of purple. Again, this is close to a 3 to 2 ratio of purple to grey. All of you were correct in your observations that the colors shift around the circumference of the swatches – and due to the differences in the number of stitches, the colors stack up very differently for different numbers of stitches.

Zgma commented:

“It doesn’t look like a self-striping yarn to me. The striping you got in the top sample is a result of the colors pooling in a way that looks like stripes, not actual “self-striping”. When yarns are labeled self-striping, it is because the runs of color are large enough that for the project intended (as in, socks for self-striping sock yarn), the color will last for all the stitches in at least one round or row, usually more. When a particular color (for instance, the black in your sock samples) lasts for part of a row, but then in the next row the color occurs before or after it did in the previous row in such a manner that it looks like striping, it doesn’t mean that the yarn is self-striping – just that it is prone to pooling in a stripey way.”

Yep, you are right about that.

To each of those that took the time to comment — thanks! I learned a great deal about pooling and variegated yarns.

I did a little internet surfing on the subject, as well. I found two informative posts about Pooling — One from the Yarn Harlot and the other from Knitting Sutra.

So – I am not really sure if I like this particular yarn – but I have decided to proceed with using it to knit a pair of plain vanilla socks. I am going to use US 2 (2.75 mm) needles with a gauge of 6.25 spi and cast on 54 stitches (this should fit my foot). I’ll post pictures of the final result.

Wow. I can’t believe there was that much difference in the pooling just by changing the number of stitches. I believe it now for sure. This is really helpful!

Knitting Socks in Waiting AreaKnitting Socks in Waiting Area

Yesterday, I had the role of being supportive of my DH while he underwent some tests at our local hospital. (Nothing serious, just part of routine maintenance for the over 55 crowd.)

Anyway, I decided to take along a pair of socks I am knitting as my “keep occupied” project for the time I would be sitting in the waiting area. I am doing cuff down, two at a time on 2 circular knitting needles. So I pulled out my knitting and started to knit away while I sipped on a cup of coffee. An older woman walked into the group of chairs where I was sitting — and pulled out her knitting!

She was knitting something on dpn’s in a pretty dark green yarn. For a time, we sat and knit without any conversation. Then, she put away her knitting and came over and sat next to me and chatted. (I think she was anxious about whomever she was waiting for, but she never really said.) I learned that she was working on a pair of mittens and she was very curious about the method I was using for knitting socks and my self-striping yarn. We exchanged bits of information about yarns and knitting and then she was called to go back with her family member while he/she recovered.

It’s interesting how knitting forms a link and an introduction for us. I know it made the time in the waiting room go by more quickly for me and I’d like to think it eased my companion’s anxiety a little and helped her time in the waiting room pass more pleasantly.

P.S. Started the socks so that I would have an easy knit project for the knitting guild meet ups. More on the guild in another post. I promise to post a picture of the socks when done.

Stitch Patterns – Garter Stitch, Stockinette Stitch & Reverse Stockinette StitchStitch Patterns – Garter Stitch, Stockinette Stitch & Reverse Stockinette Stitch

I have decided to blog about various stitch patterns from time to time. So I am starting with the time honored basics: the garter stitch, the stockinette stitch and the reverse stockinette stitch.

This discussion assumes you know how to do a knit stitch and a purl stitch. If you are new to knitting and are not familiar with these two stitches, click on this link: http://www.knittinghelp.com/videos/knit-stitch.

Garter Stitch: this stitch pattern is made by knitting every row, turning your knitting at the end of each row. (You would get the same effect if you purled every row – but most knitters prefer to knit every row). If you want to knit garter stitch “in the round”, you would knit one row and then purl one row – so most patterns using garter stitch are for flat pieces rather than circular knit pieces. The pattern produces a knitted fabric with ridges on each side that is essentially reversible – it looks very much the same on the right side as the wrong side. It takes two rows to make 1 ridge. The garter stitch is great for borders because it will not curl and lays flat once knitted. Many afghan and baby blanket patterns have a garter stitch border and it is often used as the basis for wash clothes and placemats.

Stockinette Stitch: this stitch pattern is the most commonly used knitted fabric. This stitch pattern produces a fabric with flat “V” shaped stitches on the right side and bumpy stitches on the wrong side. It is also known as flat knitting, tricot or jersey knit. Stockinette stitch consists of knitting one row, turning your work and purling one row if you are knitting a flat piece. If you are knitting in the round, you knit every row. Stockinette stitch fabric curls on the edges and at the top and bottom – it makes a good fabric for the body of a garment, but usually requires another stitch pattern for edging and or borders. It also stretches lengthwise when worn.

Reverse Stockinette Stitch: this is exactly what it sounds like – it is simply stockinette stitch fabric used with the purl side as the right side. It has all the properties of the stockinette stitch, but in addition, it will also stretch widthwise. You can see how the 3 stitches differ in the picture below:

If you look at the pictures of my teddy bear baby blanket – you will see how the teddy bear is formed by using the stockinette and reverse stockinette stitches together to form the pattern. This is a good example of how they can be combined to form textured patterning. Aran knitting patterns often combine stockinette, reverse stockinette and garter stitches as part of the textural patterning. Again, here are examples where the stitching is actually very straightforward and easy – but produces a fabric that looks complex because of the wonderful textures.

Cast On MethodsCast On Methods

This is the first post about Cast Ons. There have been several books written about different cast on methods as well as many chapters in general knitting references and YouTube videos. What I know now as a long time, more experienced knitter is that there a lots and lots of different ways to accomplish the task of putting the first stitches on your needles so that you can begin to knit. But when I first started knitting, I only knew one way to cast on. That’s because, as I believe is the case for most beginners, I was only taught one way to cast on. And I suspect that my knitting teacher taught me that cast on because it was the method that she knew.

While visiting my older sister, I learned to knit from a woman who sold yarn kits and gave knitting lessons in her apartment. So, my first knitting project was a slipper pattern kit that came with the yarn, a set of needles and an easy beginner level pattern. I think I had maybe two lessons from her and I was off to knit on my own. My teacher taught me the “Knitted Cast On” method. I used this method for a long time before discovering another cast on method – the “Backwards Loop (or E-wrap)” cast on.

The first time I encountered the notion that there were other ways to cast on was when I was knitting my very first sweater and I ran into an issue and needed some help with my project. Now, I lived in a very small town and there weren’t many people who knew how to knit. My mother located a neighbor who did and was willing to help me, so I went over to her house with my sweater. The neighbor did help me get my problem fixed – but what I remember most clearly about this session was what she said about my cast on: “Oh, you cast on wrong.”

My 11 year old self didn’t comment on that statement, but I was doing a slow burn because “I DID Cast on the right way.” I had used the knitted cast on that I knew. A lot of time passed between this incident and my learning that there are many ways to accomplish the same thing in knitting. And – I am still learning different ways to cast on!

So, in this series of posts about cast ons, I will discuss the cast ons that I currently know how to do and when and with what projects I use them. Since it was the first one I learned, I’m starting with the Knitted Cast On.

The knitted cast on is an easy cast on to learn as a beginner. Essentially, you create your first stitch on your needle by making a slip knot, placing it on the needle and start the cast on by knitting a stitch through the loop using your other needle. Once you have the stitch on the right hand needle, you slip it back onto the left hand needle and tighten it up a little, then knit into that stitch and repeat the process until you have the desired number of stitches.

Where I use this cast on:

When I want a fairly firm , yet somewhat stretchy edge: project like scarves, some shawls, blankets
Casting on for underarm stitches or thumb gussets in gloves or mittens
