Things 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!

Swatching. Yeah I’ve not been good about doing it. I need to get into the habit though.

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:

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.
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.
Knit the wrong side row to indicate where the change in needle size occurs.
Change to the US 7 and knit in stockinette stitch for another 3-4 inches.
Repeat steps 3 & 4 with the US 8. Bind off loosely. (You can also just put the live stitches on waste yarn).
Take stitch and row gauge measurements for all needle sizes and make note of these before blocking per step 7.
Block this swatch using the care instructions on the yarn label.
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”.
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:

FO: Fancy Feet Anklets – “Monday”FO: Fancy Feet Anklets – “Monday”

It’s been a busy summer and I haven’t done much posting of late. Now that summer is winding down along with the Labor Day weekend, I intend to post a bit more often. So I will start with my latest FO. Awhile back, I purchased the “Fancy Feet Anklets” kit from Knit Picks. This kit contained 7 balls of Comfy Fingering weight yarn in 7 different colors and a set of 7 patterns, one for each day of the week. The idea being that you have a pair of anklets for each day of the week. Now, I have to confess that this kit has been hanging around it my stash long enough that it is no longer available on the Knit Picks website. (I just checked.)

I started knitting one of the patterns in the kit (Monday) earlier this summer when I was looking for a small, portable knitting project to take with me here and there as we traveled throughout the summer. This was a perfect portable project. The Monday pattern is a feather and fan type lace pattern. I used the colorway Blackberry and size US 0 (2.00 mm) circular needles, 47 inches long so that I could do magic loop and two-at-a-time. Now, because this is a lace pattern, it does require keeping track as you knit. The anklet is knit toe-up — which is not my preferred method for doing socks — but I think it is the most practical way to knit this type of short ankle sock.

A couple of comments/notes to myself for the next pair: The socks seem a bit too tight across the middle of my foot, so I think I will knit the next pair on slightly larger needles. The socks are also a wee bit short for my size 8.5 foot, so the next time I will knit them about 1/2 longer before starting the heel. The heel on these anklets is made by doing 60 short rows (yep, 60). You really have to keep track of where you are in the pattern when knitting the heel. I found it best to do the heel in one long stretch of knitting rather than attempting to stop somewhere in the process. I also have decided I really don’t like the wrap and turn technique used for the short rows, so the next pair will be knit using a different technique.

I like the socks, but since they don’t really fit me, my sister (who has smaller feet) will be getting this pair.

Helpful Swatch Part 5: Substituting One Yarn for AnotherHelpful 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. “
