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.

  1. 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!

Part 2: Freeing Yourself from a Pattern – Step 1, Take Good MeasurementsPart 2: Freeing Yourself from a Pattern – Step 1, Take Good Measurements

In my last post, I outlined how to use EZ’s Percentage System to design a sweater. Today, I will spend some time answering a question from Amanda, who asked, “What do you do when the pattern does not have instructions for YOUR size?”

This is very frustrating for those of us who are either smaller or larger than the range of sizes given by the pattern designer. I have never fully understood why some designer’s only develop their patterns for “Small, Medium, & Large”, though the trend seems to be to at least go up to “Extra Large” in current knitting publications. But, if your measurements do not correspond to the designer’s definition of “medium”, you may still find yourself with a sweater that is not well-fitting.

Isn’t that the goal for all of us? To knit a well-fitting garment? So, once again, the answer is to use the pattern as a general guideline and develop your own sweater according to your own measurements. Your measurements are your starting point.

There are two ways to take your measurements:
#1: Take measurements from a sweater that fits you the way you like/love.
Lay the sweater out flat on a table or other flat surface and take the following measurements:

The Chest Measurement [CM] – this is the widest point of the sweater, usually right below the underarm. Measure from side seam to side seam. Remember that since you are measuring with the garment laying flat, that the actual chest measurement is twice this amount. (Important if you will be knitting in the round).

Shoulder Width[ShW] – this is the measurement across the shoulders from the seams or the point where the arm meets the body. This measurement is important for a proper fitting sweater.

The Neck Measurment [NM] – measure this for both the front and the back and note if the garment has shaping that creates depth – due to a difference in the front neckline from the back.

Armhole Depth [AD] – measure from the top of the sleeve at the shoulder seam down to the underarm.

Sleeve Length [SL] – measure from the top of the sleeve at the shoulder seam to the beginning of the sleeve.

Wrist Measurement [WM] – measure the width of the wrist at the bottom of the sleeve.

Sleeve Width [SW] – measure the widest part of the sleeve.

Side Seam Length [SSL] – measure from the bottom of the sweater to the point where the sleeve meets the body at the underarm.

Back Length [BL] – at the center of the back – measure from the center of the back neck edge to the bottom of the sweater.

Front Length [FL] – at the center of the front (or front edge if a cardigan) – measure from the front neck edge to the bottom of the sweater.

Other measurements that you may want –
width of sleeve at the elbow
width at waist (if sweater tapers in at the waist)

I am including a diagram that you can use to record these measurements – click here: Measurements Diagram.

#2 – Take your measurements using your body.
Note – this is best accomplished with the help of a good friend. Measurements to be taken are the same as above, only taken directly from your body. You will need to figure in “ease” when calculating your pattern changes.

Now a few words about “Ease”. Ease is an extra amount of fabric that provides a garment with movement and shaping. When you take your measurements from your sweater – they will include the ease of that sweater. When you take actual body measurements, you will need to add in an appropriate amount of ease.

Close fitting garments have less ease and in some cases have negative ease, while loose fitting garments may have a significant amount of ease. Generally, the guidelines are that a classic fit has 7-10% ease, a close-fit will have a negative 7-10% ease and a very loose fit may have up to 20% ease.

So, now you have all the measurements you need. Take a look at the pattern you are wanting to use – hopefully, there is a diagram in the pattern that gives the finished measurements for each size. If not, you may want to use my diagram to write them down. Make note of the differences between your measurements and those in the pattern.

Also, make note of any textured stitch patterns or colorwork patterns used in the pattern. You need to know what the base number of stitches is for the pattern repeats. This is usually something like: “7 stitches over 9 rows” or “7 stitches, plus 1 over 9 rows”. Write this down – you will need it later.

That’s enough for today. Next post: Step 2 – Analyze the pattern.

And finally…The Third Hat: Beret in Bee StitchAnd finally…The Third Hat: Beret in Bee Stitch

As you know from my previous post, I have been side-tracked with switching to a new computer and then finding that my blog had been hacked.  Well, I think I have recovered from the hack and I have all of my pictures and files transferred to my new computer — so, now to catch up and post about the third hat I started in January and finished in February.

My third hat is a beret knit in Bee Stitch.

Beret in Bee Stitch

This hat was also inspired by the thread about Hermione Granger’s hat in the Deathly Hallows, Part I, in the Harry Potter Lover’s group on Ravelry.  Again, I think the beret is fairly close to the original hat.

Bee Stitch Beret 4Details:  Hat was knit with Stitch Nation Full O’ Sheep (100% Peruvian Wool), using US Size 7 (4.5 mm) needles.  This yarn is very soft, aran weight, though I did find it a bit splinty.  The color is Passionfruit.  Stitch Nation is manufactured by Red Heart (Coats & Clark). 

When increasing for the beret, I basically doubled the number of stitches and it created a very slouchy beret, so if you’d like it a less slouchy, I’d only increase by 50%. I converted the Bee Stitch so I could knit it in the round and I wrote up the pattern to share with others, so here’s the link: Bee Stitch Beret.

Stitch Patterns – Seed Stitch, Irish Moss Stitch & Double Moss StitchStitch Patterns – Seed Stitch, Irish Moss Stitch & Double Moss Stitch

These three stitch patterns create an allover textured pattern using a combination of knit and purl stitches. As such, these three textured patterns are great for decorative borders. Between the USA and UK there is some confusion related to the Moss Stitch – I have seen references to the Moss Stitch which are exactly the same as what I know as a Seed Stitch here in the USA.

Seed Stitch (Moss Stitch):
SeedStitch
This is one of my favorite patterns for borders with the stockinette stitch. It lies flat and does not roll or curl. It is reversible and I love it for front bands on cardigan sweaters.
This stitch pattern is a multiple of two and a repeat over two rows. The first row is the same as a 1 X 1 ribbing: K1, P1 across the row. On the following row, all stitches are worked the opposite of the way they face you – i.e. you purl the knit stitches and knit the purl stitches. Seed stitch tends to expand widthwise and is wider than the same number of stockinette stitches.

Irish Moss Stitch:
IrishMossStitch
This stitch has a diagonal texture. It is a multiple of two stitches with a repeat over four rows. The first two rows are knit the same as 1 X 1 Ribbing: K1, P1 across the row. Then the next two rows are knit the opposite: P1, K1 across. You repeat these four rows to make the textured pattern.

Just like the Seed Stitch, the Irish Moss Stitch creates a reversible fabric that lies flat and does not roll or curl. The fabric will tend to expand crosswise and the stitches may “seat” themselves after washing. If you are using this pattern stitch as the main body of your garment, it is best to knit the garment to the actual measurements of the chest of the intended wearer before the first washing.

Double Moss Stitch (Double Seed Stitch, Box Stitch):
DblMossStitc
This stitch pattern is a multiple of four stitches repeated over four rows. The first two rows are the same as 2 X 2 Ribbing: K2, P2 across the row. On the next two rows, you do P2, K2 across. It has essentially the same properties as the Irish Moss Stitch. This pattern is wonderful for knitting textured scarves that do not roll or curl on the edges.
