Helpful Swatch Part 5: Substituting One Yarn for Another

Many times a knitter will select a pattern to knit only to discover that the yarn used in the pattern is either not available or there isn’t a sufficient quantity available for purchase or it costs more than what the budget allows. So, that leads to finding a reasonable substitute to use. I have seen many forum posts in Ravelry where knitters have had difficulty making a proper substitution.

The first step in substituting one yarn for another is to look for a yarn of similar fiber composition that has approximately the same weight and recommended gauge as the yarn listed in the pattern. By this, I mean if the yarn used in the pattern is worsted weight (size 4), it’s best to find another worsted weight yarn to use as the substitute. If you are purchasing from a local yarn shop, the staff may help you find a substitute. If shopping online, Yarnsub.com is a helpful website that can be used to guide your initial search. Another resource is Ravelry – if the pattern is available in the Patterns database, you can look at others’ projects to see what yarns have been used. Regardless, once you pick your substitute yarn – you’ll need to swatch to find your gauge before you cast on and begin knitting the pattern.

Question: “I’m not getting the same gauge with my substituted yarn as the gauge stated in the pattern – what do I do now?

Here are some options to consider:

Change needle size and reknit the swatch to see if you can match the gauge. If you are getting more stitches than the stated gauge – go up one or two needle sizes. If you are getting fewer stitches than the stated gauge – go down one or two needle sizes. If you succeed in matching gauge with the change in needles and you like the fabric you are producing, then simply follow your pattern and knit with the size needle that helps you get gauge.
If you still can’t get gauge after changing needle sizes, but you like the fabric you are getting, calculate the number of stitches you need to cast-on to match your chest measurement and check the pattern to see if there is a size that uses the same number of stitches. You may still need to make adjustments in shaping if your row gauge is different from the pattern.
Use the pattern as a guide only – use the schematic plus any adjustments you need to make and then determine the stitch counts and rows needed to make the garment with your own gauge. (A good reference for this is Knitting Pattern Essentials by Sally Melville)

Here’s the next issue for substituting one yarn for another: Does the substitute have the same weight and yardage as the original yarn? If it does – you are in luck and can simply buy the same amount of yarn as what is given in the pattern for the size of the garment you want to knit. (Remember to buy an extra one for swatching.) However, in most cases there is a difference in yardage and/or weight between the substitute and the original yarn – which leads to the question: “How much of my substitute yarn do I need? This brings us back to the basic math I covered in my previous post: “To determine the number of skeins, balls or hanks of yarn you need: Divide the number of yards by the number of yards in the skein. Or divide the total number of grams by the number of grams of the skein. Remember that you will want one extra skein for swatching. “

In my last post, I went through all the necessary measurements you need to take in order to ensure that you can modify or create any sweater pattern you wish.
If you haven’t done so, you may want to go back and read this information and take your measurements.

Today I will discuss how to analyze a written pattern so that you can use it as a guideline to knit your own well-fitting garment. First, get your favorite sweater – you will be using it to help you analyze the pattern you have selected.

Now, let’s take a look at this sweater – you need to understand what it is about this sweater that makes it your favorite. Is it a pullover or a cardigan? Is it close-fitting or loose? How long is it? What type of sleeve does it have (Set-in, drop, raglan or other)? What type of neckline ( Round, V-neck, Boat Neck, Square, or other)? Now compare this information to the sweater pattern you want to knit. Just a word of caution, here, if the pattern you have chosen differs dramatically from your favorite sweater – you may not be happy with the end result. Then, again, if it is a conscious choice, you may.

Now let’s look at the sizing given in the pattern. Sizes are often stated as “Small, Medium, Large, Extra-Large”, etc. Some patterns will give sizing using finished chest/bust circumference, while others will state the sizing in terms of actual body measurements. If the pattern sizing is in terms of finished measurements, it will have the ease incorporated into it. If in actual body measurements, you may have to determine how much ease is factored into the garment. The amount of ease is both a matter of personal preference and a property of the design of the sweater. To determine how much ease you prefer – pull out your favorite sweater, measure the chest and compare the measurement to your actual body measurement. The math is simple: Subtract your body measurement from the garment measurement – this will give you the amount of inches of ease.

Now – take a look at that pattern you are considering– is there a size that matches your actual chest measurement PLUS that amount of ease? If the answer is “Yes” – then, if your gauge with your yarn matches the pattern, you are good to go.

If you find that your size is not represented within the pattern, you will need to adjust the body width.

For a body width less than the smallest size given in the pattern, recalculate the number of stitches to cast on and then follow the directions for the smallest size.

For a body width greater than the largest size given in the pattern, recalculate the number of stitches to cast on and follow the directions for the largest size.

For a body width that is in between sizes, recalculate the number of stitches to cast on and then follow the directions for the closest size.

In all cases, the formula is: SPI (your gauge) X body width

There are some additional elements to consider and modify if you are adjusting body width:

If the sleeve is a drop sleeve design, be careful not to add too much body width or the shoulders will be too wide. If you need more width in the hip area than the shoulders – use an A-Line shape for the body – which means that you will need to factor in some decreases from the hip to the underarm.

If the sleeve is a set-in sleeve design, remember that as you change body width, you must also adjust the shoulder width because the top of the sleeve should hit the end of the shoulder.

The sleeve length must be adjusted when adding or subtracting body width. This is because if you add width or subtract width to the body, you have also done so to the shoulder width – and shoulder width contributes to the total sleeve length. Verify the length you need for your sweater and make adjustments accordingly.

Additional considerations in modifying a written pattern:

Does this pattern incorporate a textured or colored stitch pattern? If so, what is the base stitch pattern? To determine this, look at the instructions and the graph for the stitch patterning. Most stitch patterns are a multiple of a base number of stitches – i.e. 8 stitches over 24 rows. So, if you are reducing or increasing the number of stitches to cast on – you will need to adjust this number so that it divisible by your base stitch pattern. For example: You have determined that you need to cast on 214 stitches and your base stitch pattern is an 8 stitch repeat. If you divide 214 by 8, you get 26.75 – which is not a even number. You will need to increase the number of stitches you cast on to 216 – which is evenly divisible by 8.

Today, I have discussed how to use a written pattern as a guideline and modify it so that it will fit properly. This works best if your gauge matches the pattern, but your measurements do not.

Next post, I will discuss the notion of designing your own sweater from your choice of yarn, a basic design and the stitch pattern of your choice.

Master Knitter Level I – Swatches #7, #8, & #9 – DecreasesMaster Knitter Level I – Swatches #7, #8, & #9 – Decreases

Swatches 7 through 9 are demonstrations of various decrease techniques.

Swatch #7

Swatch 7 demonstrates “Blended Decreases” using SSK (Slip, Slip, Knit) on the right edge and K2Tog (Knit 2 Together) on the left edge.

SSK is a left-slanting decrease and is made by slipping 1 stitch as if to knit, then slipping a second stitch as if to knit, then inserting the left needle into these two stitches and knitting them together.

K2Tog is a right-slanting decrease. K2Tog decreases are the basic decrease every knitter learns. You simply insert the right needle into two stitches on the left needle and knit them together.

I have had difficulty finding a reference that actually defines “Blended Decreases”. Through my research it appears that “Blended Decreases” are decreases that slant or slope in the direction of the desired shaping. In this swatch the left-slanting decrease on the right edge and the right-slanting decrease on the left edge slope in toward the center of the swatch.

Swatch #8

Swatch 8 demonstrates SKP (Slip, Knit, Pass Slipped Stitch Over) and KSP (Knit, Slip, Pass stitch over) decreases.

SKP decreases are also sometimes written as S1, K1 PSSO in patterns. This is a left-slanting decrease and is done on the right edge of the swatch. Any decrease that requires you to pass a stitch over another one results in a somewhat uneven stitch due to the stretching that occurs when you pass the stitch over.

The KSP decrease was a new method for me. It is a right-slanting decrease that mirrors the SKP decrease and was knit on the left edge of this swatch. KSP is done by knitting a stitch, then slipping the stitch back on the left needle and passing the stitch over the next stitch with the right needle, then slipping the stitch back from the left needle to the right needle.

Swatch #9

Swatch 9 uses the K2Tog and SSK decreases but is different from Swatch 7 in that the K2Tog is done on the right edge and the SSK is done on the left edge.

TKGA refers to this swatch as “Full Fashioned”. I have not found a specific definition for the term “Full Fashioned” in my references. However, two of my sources refer to full fashioned decreases as decreases that are done with 2 or more stitches on the edge, making the decreases more visible and part of the intended design of the knitted fabric. In this swatch, the K2Tog decrease on the right edge slants to the right and stands out against the slope of the fabric. Likewise the SSK decrease on the left edge slants to the left and stands out against the slope of the fabric on that side. These decreases are more visible than those in Swatch 7.

Things Learned from a SwatchThings Learned from a Swatch

It took me years to appreciate the value of doing a swatch before starting a knitting project. I cannot tell you how many poorly fitted sweaters I knit before I came to realize that it truly was worth the time and effort to swatch first.

I learned this when I bought my first knitting machine. You see, when you are using a knitting machine, you can’t even get started without doing that swatch – as you need it to tell you if you have your machine tension set up correctly. It only takes one frustrating experience with a too tight tension on the knitting machine to convince you of the necessity for doing a swatch or two.

Swatching also provides you as a knitter the freedom to become, as Elizabeth Zimmermann says, “The boss of your knitting”. If you know your gauge, and understand the basics of the design you are wanting to make – you are free to modify any pattern – or MAKE YOUR OWN.

So, I always swatch. This last weekend I did a swatch using the Baby Ull yarns that I purchased to knit a sweater and romper for my new grandson due the end of January. I had a couple of extra reasons for doing this swatch beyond determining what size needle I needed to obtain the stated pattern gauge. First, I wanted to try out the three color pattern for the sweater and get comfortable with it. Second, I wanted to see if I liked the color combinations of the yarns in the color pattern.

Swatch_Cardigan1 Here’s a picture of the swatch. I cast on 44 stitches so that I could have a 40 stitch area surrounded by a 2 stitch garter stitch edging. I started using US 2 (3.00 mm) needles and then switched to a smaller US 1 (2.50 mm) needle for the last part of the swatch. I did a section of garter stitch, then stockinette stitch, then the color pattern using the lighter aqua blue as the main color and then switched to using the darker teal blue as the main color. I finished the swatch by doing a section of sockinette stitch on the smaller needles, followed by a section of garter stitch.

Here’s what I learned from this swatch: 1) I need to use smaller needles than what is stated in the pattern in order to obtain gauge. This is important because I want this sweater to fit. 2) I like using the darker teal blue as the main color – I think the lighter aqua blue shows up better against it than the other way around. This is significant – because I bought 7 balls of the lighter aqua and only 1 ball of the darker teal. (I have now ordered enough teal to make the sweater, as my LYS did not have enough of it on hand…) 3) The 3 color pattern is fairly simple and easy to knit. I think it’s good to practice such things before starting off on a special project like this.

So to those readers who “hate to swatch”: do you see the value of what I did here? Swatching is a valuable technique that helps you be the “boss of your knitting”. Now go swatch!
