How to Knit a Helpful Swatch – Part 3 Swatching in the RoundHow to Knit a Helpful Swatch – Part 3 Swatching in the Round

It took me a good bit of time to decide if I thought it was necessary to knit swatches in the round if I was knitting an item in the round rather than flat. The practice of knitting sweaters flat in pieces that are sewn together versus knitting sweaters in the round is, in itself, a whole topic with proponents for each practice.  I may take this topic up at a later time, but for now I will focus on knitting a swatch in the round.

First, there are many knitters and designers who only use gauge swatches knit flat to determine their stitch gauge even if the pattern is knit in the round, and second,  most patterns do not state how the gauge swatch was done. All you see in the pattern is the gauge statement.

Do you know if your gauge is the same if you knit in the round as when you knit flat? There’s a good chance that it’s not. As I’ve said before, gauge is a measure of how an individual knitter knits.

Think about how you knit when you knit in the round. One of the biggest differences is that you only knit on the right side of the fabric when you knit in the round. Using stockinette stitch as an example: When you knit flat, you knit one row (right side) and then turn your work and purl the next (wrong side). When you knit in the round, you join the stitches to make a circle and then knit every round.

Now, if you are one of the many knitters whose purls are looser than their knits, there is going to be a difference in tension between something you knit flat and something you knit in the round. Plus, you may modify your technique for knitting when knitting in round from when you knit flat. If you use straight needles when knitting flat, then switch to using circular needles or double point needles (dpns) to knit circular – your gauge may be significantly different. This is why I have come to the conclusion that it is good practice to swatch in the round when planning a project that will be knit in the round.

So how does one knit a swatch in the round? The first method is to cast on a enough stitches to give you a knitted tube that will be at least 4+ inches when laid flat. This could be the start of a sock or a hat. (Elizabeth Zimmerman said that “a hat makes a good swatch”.) Once you have a tube knitted of sufficient length for a good  measurement, you treat this swatch the same way you would if your swatch that was knitted flat – i.e. measure, block, re-measure.

The second method goes by a couple of different names: “Speed Swatch” and “Circular Swatch with Floats” are two that I have found in my research. In this method, you use a circular needle and cast on the same number of stitches you would if you were knitting flat. But instead of knitting a row and then turning the swatch and knitting back to the end of the row, you slide your stitches to the needle on the opposite end and strand the working yarn loosely across the back and start knitting the next row. You keep repeating this process until you have a long enough swatch for good measurements. See pictures below:

Once you have the swatch completed, you treat it the same way as any swatch – measure unblocked, block, re-measure. A note about measuring this swatch: Some sources suggest that it is easier to measure this swatch after cutting the loose strands so that the swatch will lay flat. Others simply say to measure the swatch by laying it as flat as you can. Logically, you are not going to want to cut the strands if you plan to reuse the yarn in the swatch. I’ve tried both ways and did not find a significant difference in measurements.  Here are pictures of the swatch above after I blocked it and cut the floats to take the measurements:

So if you plan to knit a sweater in the round, please do your swatch in the round.

How to Knit a Helpful Swatch – Part 2 Stitch PatternsHow to Knit a Helpful Swatch – Part 2 Stitch Patterns

In my previous post, I discussed how to make a preliminary swatch to select the size needle that gives you a fabric that you like and then how to knit a gauge swatch. The gauge swatch is measured to give you your stitch gauge (stiches per inch) and your row gauge (rows per inch).

At this point, you might think you are ready to cast on and begin knitting your sweater – BUT….

Are you planning on using some type of ribbing for the bottom, cuffs and neckline of the garment? Are you planning on using a certain textured stitch pattern, a lace pattern or cables in your sweater? Will you be combining two or more stitch patterns in the body of the sweater? If the answer to any of these questions is “yes”, then you need to do more swatching.

Swatches with Borders: Have you ever knit something with a definite edge made by knitting either garter stitch or seed stitch and then found that the edges curl? The reason this happens is usually due to a difference in gauge between the stitch pattern used for the border and the stitch pattern used for the body. Thus, if you are knitting piece with a border that is different than the body of the piece, knitting a swatch with the borders on it provides you with an opportunity to make adjustments to minimize or eliminate the problem.  Suzanne Bryan has a nice video on this that you may find helpful, here’s the link:

Short Rows in Garter or Seed Stitch Border

Note: I don’t recommend using garter stitch borders on gauge swatches even though others do. The border tends to distort the swatch and may affect the accuracy of your measurements.

Swatches of Ribbing: Ribbing by nature tends to “pull in”. Which means that 30 stitches of ribbing will have a smaller width than 30 stitches of stockinette stitch. How much of a difference can be quite significant and affect the way the garment fits around the hips and neck as well as around the wrists on a long sleeve. Also, some knitters find that their ribbing stitches appear larger than their stockinette stitches due to changes in tension. One solution for this is to use a smaller needle when ribbing – but if you do that you may need to have more stitches to get the right width of fabric for a proper fit. Knitting a swatch with your selected ribbing pattern followed by a transition to the stitch being used for the body of the sweater will provide you with the information you need to decide what you want to do. You might want to knit separate swatches with different ribbing patterns to select which ribbing you prefer to use in your garment. (You don’t have to use the same ribbing that the designer did for the pattern if you don’t want to…just saying.)

Swatches of Stitch Patterns:

In this post, stitch patterns refer to textured pattern stitches, lace patterns, cable patterns, etc. Basically any grouping of stitches that combine to make a pattern from the variations in stitches used.

I think making a swatch of the stitch patterns used in a written pattern provides a great deal of useful information about how the finished garment will look and feel – and fit! It’s also good practice before doing it as part of your finished item.

Keep in mind that most written patterns only give gauge in stockinette stitch and while that tells you what the designer’s gauge is – it does not tell you how the gauge changes in the stitch pattern(s) used in knitting the garment. If you find a written pattern that states the gauge of the stitch pattern – great. But does your gauge match that? Swatching is the only way you will know.

If you are only using one stitch pattern, then knitting a swatch with two or more pattern repeats will help you figure out how the pattern affects the width and length of the garment and what adjustment you might need to make to obtain the correct size of garment you want. If you combine it with your ribbing, you will see how the ribbing affects the transition to the main fabric of the garment.

If you are combining more than one stitch pattern within the main fabric of a garment, I recommend doing individual swatches for each stitch pattern to use as a gauge swatches.

Then to see what happens when the stitch patterns are combined,  you should do a swatch large enough to include all of the stitch patterns used in the order you plan to use them. This may end up being a very large swatch – even enough stitches for the back of your garment. This type of swatch will provide you with a lot of helpful information and give you insight into what adjustments you might need to make for a great fitting garment.  More on this in a later post.

How to Knit a Helpful Swatch – Part 1 GaugeHow 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:

Do You Know? Swatching 101Do You Know? Swatching 101

This is the first in a series of  blog posts about swatching. It has taken me years to gain an appreciation for swatching and I frequently see posts in Ravelry forums about issues coming from swatches. If you are on Ravelry, you have probably seen them too. There are usually a number from new knitters/beginners that ask why the sweater they just knit according to a pattern doesn’t fit and many times, these knitters either didn’t swatch at all or didn’t knit a proper swatch. So, this set of posts is intended to share what I have learned over the years about swatching.

Take my quiz below to check your understanding of swatches.

Question 1: True or False: A swatch must be 4 inches by 4 inches (10 cm X 10 cm).

Question 2: True or False: The needle size stated in the pattern is the size needle you must use to obtain the pattern’s stitch and row gauge.

Question 3: True or False: Row Gauge is not important.

Question 4: True or False. Swatching is necessary for knitting sweaters and other fitted garments.

Question 5: True or False: You must get gauge when knitting from a pattern.
