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.

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:

Yarn SubstitutionYarn Substitution

Substituting yarn

The question comes up every so often at the knitting meet-up and in the Ravelry forums. It takes the form of “Can I use this yarn instead of that yarn?” and any of a number of variations. And the answer is almost always: “It depends.”

Oh, we want this answer to be a simple “Yes”. But it seldom is. Usually the knitter has a valid reason for wanting to use a different yarn than what was used in the printed pattern: Lack of availability, wanting/needing a different colorway, dislike of the particular yarn, etc. If the knitter happens to select a yarn of similar weight and make-up, the substitution will probably go reasonably well – providing, of course, that the knitter can achieve the stated pattern gauge with the chosen yarn. This is the happiest of all occurrences – the yarn you want to use works out well with the pattern and you can just relax and knit happily on your project.

The subject of matching gauge could constitute the contents of an entire article, if not a book. For the sake of brevity, I will simply state that gauge is essential and that any knitter who wishes to produce a well-fitting garment needs to pay attention to gauge – IF she is following a pattern that contains the concept of “fit” as part of the design. (Gauge is less important with scarves & shawls).

Lindy’s Advice #1: When substituting yarns, it is best to select a yarn that is of the same weight and has the same characteristics as the original yarn. But do a gauge swatch to make certain you do not need to make adjustments so that the garment fits correctly.

Perhaps the most frustrating of experiences with yarn substitution is the situation where you have selected a yarn of similar weight and characteristics – but try as you may, you cannot achieve the stated gauge. The advice is usually to go up a needle size or two if your gauge has more stitches and to go down needle sizes if your gauge has fewer stitches. If this works, then wonderful! Proceed with the project. But if, in spite of the change in needle sizes, you still cannot get the stated gauge – well, this can be a significant problem. Being off a half a stitch doesn’t seem like much, but when multiplied over a large number of stitches (say 100 or more), it becomes quite significant and the result is a garment that doesn’t fit properly. You have two options in this situation: 1) try a different yarn (yep, try another one) ; or 2) get out your calculator and start calculating the adjustments needed to ensure a proper fit.

Note: If math makes you anxious and you would never consider recalculating the number of stitches you need to make the garment using your yarn and your gauge – then skip this next part.

Here are the basic calculations you’ll need to make the appropriate adjustments:

Pattern Gauge states “20 stitches and 20 rows = 4 inches” (5 stitches/inch and 5 rows/inch)

To adjust pattern width (i.e. your stitch gauge is different):
Your stitch gauge is 22 stitches = 4 inches. Which is 5.5 stitches per inch

Pattern instructions state that the back of the garment measures 25 inches at the bottom and says to cast on 125 stitches. To adjust for your gauge, you would need to cast on 25 X 5.5 = 137.5 stitches – you will need to round down to 137 stitches so that you have an odd number of stitches, since the pattern has an odd number.
You will need to make similar calculations for width measurements throughout your pattern – it is best if you go through and do this before you starting knitting.

Adjusting pattern length may or may not require some math. If the pattern has instructions that use length (inches) rather than rows, it really isn’t necessary to calculate the number of rows required with your gauge, because you can simply knit to the desired number of inches.

However, if the pattern contains instructions such as “knit 40 rows then begin shaping” – you may want to calculate the adjustments needed, as follows:

Your row gauge is 30 rows = 4 inches – which is 7.5 rows per inch

Pattern row gauge is 20 rows = 4 inches (5 rows per inch)
To calculate the number of rows you need to knit to be equal to the 40 rows called for in the pattern :
40 rows ÷ 5 rows/inch = 8 inches
8 inches X 7.5 rows/inch = 60 rows – so instead of knitting 40 rows then begin shaping, you would knit 60 rows.

A shortcut in these calculations would be to go through and calculate the number of inches that need to be knit using the row gauge of the pattern and then just knitting to the calculated length.

This can be a daunting bit of calculation – but it will result in a better fitting garment with your desired choice of yarn and is thus, worth the effort.

So far, I have discussed what considerations are needed when substituting a yarn of similar weight and characteristics with another. Now about substituting an entirely different weight of yarn…

I have attempted this several times and have not been happy with the result each time. Hence, Lindy’s Advice #2: No matter how much you love the yarn you want to substitute and the pattern, if the yarn is not the same weight and/or does not have the same characteristics as the yarn used in the pattern – DO NOT use that yarn with that pattern.

I know, I know – you really want to use this yarn, but it’s like trying to fit a square peg in a round hole. I feel your pain, I really do. But don’t do it, you won’t be happy with the result.

I think every knitter has tried using bulky yarn for a worsted weight pattern or visa versa. The results have probably been disappointing and the garment was either too big or too small. It certainly was for me.

I know of many knitters who have attempted to double-strand worsted weight or sport weight yarn to substitute for bulky weight. It can be done with some success, but once again – you have to do a gauge swatch and make the necessary adjustments for differences between your gauge and the pattern gauge. You just can’t get away from the math…

But wait! There is a way to substitute yarn so that it doesn’t drive you crazy: “Free yourself from the pattern”.

Huh? What do I mean by that? Well, as a knitter you will eventually reach a point in your knitting experience when you begin to understand the basics of garment design and construction. Granted there are literally hundreds of thousands of written sweater patterns available. But any sweater has a front, a back, two sleeves and a neck. If you understand how to construct the basic parts and match them to your desired body measurements – you really don’t need a specific written pattern.

Let’s start with that pattern you want to knit with a different weight of yarn. What are the characteristics of the garment? How are the sleeves shaped? How is the front shaped and how is the back shaped? What do you like about this pattern?

Does the pattern use a textured stitch patterning or does it have a particular colorwork patterning? Are there charts for the stitch pattern(s) or the colorwork pattern(s)? You can use these to make your own customized sweater with your chosen yarn.

How? Well, it will require some thinking, some planning, some math (sorry!) and a very good set of body measurements. Armed with the knowledge of sweater design – you can go from carefully following a written pattern to using the pattern as an inspiration for your own custom designed sweater.

I will outline how to do this in my next post. Off to find my sweater design references…
