How to Knit a Helpful Swatch – Part 1 Gauge

First, a definition: A Helpful Swatch is a swatch that gives you, the knitter, information that helps you in the planning, preparation and construction of your knitting project. It tells you a number of things that are essential for successful completion, among them:

  • Your stitch and row gauge with the yarn and needles  you have selected for your project
  • The type of fabric produced with your yarn and your gauge.
  • What happens when the yarn is washed and dried.
  • What adjustments are needed to make a garment that fits the way you want it
  • How a given stitch pattern looks when knitted using your selected yarn.

In addition, you can use your swatch to test out different techniques such as decreases or increases that you might want to use during construction. Full disclosure here: You’ll need to knit more than one swatch to get a helpful swatch. This is why most experienced knitters will tell you that you should buy an extra skein of yarn just for swatching.

One of the first issues new knitters encounter when doing a swatch is not knitting a big enough swatch  — they tend to cast on only enough to knit a 4 inch square. In most cases, this isn’t big enough to provide helpful information.  So, how big does a swatch need to be? The short answer is: Big enough to get a good sense of how the project will knit up. Elizabeth Zimmerman wrote that “a hat is a good swatch” – which is true if you are planning to knit your sweater in the round. Some knitters use a sleeve as their swatch, others knit a swatch that is at least 6 inches wide by 6 inches high. I would say that the 6 X 6 swatch is a good starting point – but you made need to make one that is even wider.

GAUGE: Here’s one inescapable truth about yarn, needles, and gauge: “Your Mileage May Vary”.  Meaning that gauge is a very personal thing – it’s yours and yours alone. It is a measurement of the fabric YOU produce when you knit. So doing a swatch to identify your gauge is important to your success.

Before you start your first swatch you need to decide what size needle works best for the project. Yarn labels usually have a recommended needle size and gauge listed. Some manufacturers state a range on the label, others use a symbol to indicate the recommended gauge. Either way, this is just the starting point. A pattern may also include information about the yarn, needles and gauge the designer used to create the pattern. Both sources provide you with a starting point for selecting the size needle you need to use to obtain the knitted fabric you want to make.

Here are the steps I follow to make a Gauge Swatch:

  1. Select 3 sizes of needles – if the recommended needle size on the yarn label is a US 7, I use a US 6, US 7, and US 8 for this swatch.
  2. Cast on enough stitches on the smallest needle size for a width of at least 6 inches. (To estimate the number of stitches to cast on, I use the recommended gauge on the yarn label. For example, the label states 20 stitches in 4 inches, that’s 5 stitches  per inch, so I’d cast on 30 stitches for 6 inches.). Knit in stockinette stitch for at least 3-4 inches ending with a right side (knit) row.
  3. Knit the wrong side row to indicate where the change in needle size occurs.
  4. Change to the US 7 and knit in stockinette stitch for another 3-4 inches.
  5. Repeat steps 3 & 4 with the US 8. Bind off loosely. (You can also just put the live stitches on waste yarn).
  6. Take stitch and row gauge measurements for all needle sizes and make note of these before blocking per step 7.
  7. Block this swatch using the care instructions on the yarn label.
  8. Once the swatch is dry, take stitch and row gauge measurements for each needle size and write them down in your project notes. These are your “finished gauges”.
  9. Select the needle size by looking at the fabric produced by each size needle. Which one gives you the best fabric? Do you like the stitch definition? Do you like the way it drapes and feels? Is one better than the other two? It’s your choice – but this helps you select the needle that works best with you and your choice of yarn.

Measuring the Swatch for Gauge:

Stitch gauge is expressed as “number of stitches in number of inches (or centimeters)”. You may see this as “20 sts/4 in (10cm) or 5 sts/in.  To determine your stitch gauge you need to count the number of stitches in a horizontally measured row of stitches. This measurement should be taken using a ruler and marking the starting point and ending point away from the edges.

Row gauge is expressed as “number of rows in number of inches (or centimeters)”. You may see this as “28 rows/4 in( 10cm) or 7 rows/inch. To determine your row gauge you need to count the number of rows in a vertically measured column of stitches. Again, the measurement needs to be taken using a ruler and away from the top and bottom edges of the swatch.

Note that it is not necessary to measure just 4 inches horizontally or vertically. If you measure more than 4 inches, you may get a more accurate gauge because it will give you a better average – yes – gauge is actually the average number of stitches or rows per inch. And, math is required to determine gauge.

There are any number of YouTube videos available on measuring gauge swatches to determine stitch and row gauge. I recommend the following ones for more detailed explanation:

Update on Progress with SFS Team-Knit SocksUpdate on Progress with SFS Team-Knit Socks

SFS_TK_Heels1I knitted the heel and had about half of the gussets done on these socks when I decided that I did NOT like the way the picked up stitches for the gussets looked. They weren’t tight enough and appeared to have small holes along the picked up edge. Frustrating, VERY frustrating – especially since these socks must be knit to very high standards. I don’t know if the problem is the way I picked up the stitches – or if I pulled the yarn too tight. I have found that the Regia Stretch yarn used for these socks can be overstretched – it is a very stretchy yarn.

I put the socks in “time out” over the Christmas holidays – just too stressful to deal with them given all the other demands of the season. Last week, I pulled them out, put in lifelines at the instep and the end of the heel turn and then frogged them back to the point where I need to pick up the gusset stitches. 🙁

I plan to tackle the picking up of the gusset stitches this week, paying special attention to how the stitches form as they are picked up…and trying to avoid overstretching the yarn…I will let you know how it goes.

A Study of Pooling in a Variegated Sock YarnA 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.

How to knit a Basic Beanie without a pattern – Part 1: Brim and BodyHow to knit a Basic Beanie without a pattern – Part 1: Brim and Body

I have read several Facebook posts and Ravelry forums where new knitters are asking about how to knit a basic hat. There are many basic beanie style hat patterns available for free on Ravelry, including one of mine: Basic Beanie Hat.

But the truth is that a basic beanie hat is fairly easy to knit without any pattern if you are familiar with its structure and know your gauge for the yarn you want to use for the hat. So this post is about the basic structure of a beanie, knit in the round.

Now, a beanie can be knit top down or bottom up, but if you look at most patterns, they are written with a bottom-up construction and this will be the approach I will follow here. There are three parts to a basic beanie: The brim, the body, and the crown. The brim of a beanie is usually done in either 1×1 ribbing (k1,p1) or 2×2 ribbing (k2,p2). The length of the brim can be relatively short – and intended to not be folded, or it can be longer so that it will be worn with the brim folded.

The body of a beanie is the part of the hat that covers the head from just above the ears to where the crown is formed. The length of the body varies according to the size of the hat, with children’s hats being shorter than an adults’ and Men’s hats are usually longer than Women’s. For a basic beanie this length is approximately the length from the top of the head to the bottom of the earlobe or half the length of measuring from the bottom of one earlobe to the other up over the top of the head.  

The crown of a beanie is the area that covers the top of the head and is shaped by making decreases to form a circle that is closed at the very top.

To begin knitting the basic beanie you need to do a little math. You need to know what circumference you want it to be. If you have the measurement of the circumference of the head of person you want to fit, you can use that. If you don’t know the circumference, then you can use a standard size chart for the measurements. See the chart below. For a women’s head, I usually use a circumference of 21 – 22 inches as a starting point.

Knitted beanies are made with negative ease. Now what do I mean by that? Negative ease means that the knitted hat will be smaller than the actual circumference and I usually factor in about 10% negative ease for my beanies. This gives the hat a good fit and it hugs the wearer’s head and stays in place. Using an example of a 21 inch circumference, the knitted circumference with 10% negative ease is 19 inches. (10% of 21 = 2.1; 21-2 = 19 or if you prefer: 21 x 0.9 = 19)

You are now ready to determine how many stitches to cast on to start the brim of the beanie. For this you will need your stitch gauge in stitches per inch (spi). I usually have a gauge of 5 spi with worsted weight yarn, so in this example, I multiply 19 inches by 5 sts which gives me 95 sts. However, if I am doing 1×1 ribbing, I need an even number of stitches, so I can either round down to 94 or round up to 96 sts. If I do 2×2 ribbing, I need an even number of stitches, but the number also has to be divisible by 4. In this example, 96 is divisible by 4, so I would start with 96.

For a Women’s beanie, I usually like to knit the ribbing to a length of approximately 2 inches and then start the body. For a basic beanie, I knit the body in stockinette stitch. The body area is where you can add various textured stitch patterns or knit stripes using different colors of yarn. But the very basic beanie is knit in stockinette stitch.

The length of the hat is determined by measuring the length of the wearer’s head from the lower earlobe to the top of the crown. Another way is to measure the head from the bottom of one earlobe over the top of the head to the bottom of the other earlobe and then divide that number by 2. For a women’s hat, I usually use a length of 10.5 to 11 inches, for a men’s hat I use 11 to 11.5 inches. See the standard size chart above for further information. The crown of the hat is approximately 1/3 of the total length of the hat. So, once the ribbing is done, you knit the body to the desired length where the crown shaping starts (measured from the cast on edge). In my example of a women’s hat with a total length of 11 inches, I would knit to a length of 7.5inches. The remaining length of the hat is where the crown is shaped using decreases.

My next post covers things you need to consider to knit the crown of the beanie.
