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:

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

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.

It has been nearly 6 months since I last wrote a post. This was due in part to the fact that my office was in the process of being remodeled, as well as the busy holiday seasons (Thanskgiving, Christmas, & New Year’s). I am glad to say that my office is now finished and looks quite lovely — but I am still unpacking things. I have made a promise to myself that when I unpacked the hastily packed boxes, that I would take the time to go through them and eliminate things that I no longer used, need or want. So far I have kept that promise and I am gradually putting the things I have decided to keep in their new homes. I have 4 boxes left to unpack.

One of the most difficult tasks for me as I unpacked was to sort through the many years accumulation of knitting and crochet magazines, patterns and pattern books. I love books. And I have a lot of knitting and crochet books. I am proud to say that I was focused enough to really let go of those that I will never use and those that are really out of date. I gave a few to some of my knitting friends, but in the end — most of the old magazines ended up being recycled. Are you someone who collects books and magazines? If you are — you know how much of a struggle it was for me to finally let them go.

New Bookcase in My Office But now — I have plenty of room for NEW BOOKS! 🙂

One of the changes that I have made over my 50 years (yes, 50!) of knitting is that I no longer buy knitting patterns, books of knitting patterns or those knitting magazines that you can find in your local supermarket. As I have written in this blog before, since I first read Elizabeth Zimmerman’s Knitting Without Tears, I have moved from buying patterns to buying books on techniques and stitch libraries. These days when I see something in a magazine that I think I would like to knit — I study it for the details — i.e. the design elements, the stitchery, etc. — and then I sit down and figure out how to knit it up without the pattern — I draft my own essentially. I find I am much happier with the results.

I am doing that now — what I have on my needles is a raglan cardigan sweater, knitted from the top down — size 18 months. I hope when I finish this little sweater that I will be able to develop another sweater calculator for doing top down raglan sweaters. I’ll post it when I am certain that it works correctly.

For those of you who wish to move beyond following written patterns — Elizabeth Zimmerman’s books are a great way to start.

Stitch Patterns – Three Examples of RibbingStitch Patterns – Three Examples of Ribbing

3Ribbings

All ribbing is a combination of knit and purl stitches across a row.  When you knit back on the next row, you knit the stitches as the face you, that is, knit the knit stitches and purl the purl stitches. The knit stitches form a ridge (or rib) and the purl stitches form a valley.  Ribbing is essentially a reversible fabric.  Ribbing is elastic crosswise and will stretch lengthwise and is most often used for sweater neckbands and bottoms and the cuff of socks.   Ribbing also “pulls in” naturally, so it will effect the shape of your garment.

One-By-One (1×1) Ribbing:

1x1Ribbing

This is knitted exactly as it says.  Knit 1 stitch, purl 1 stitch across the row.  (Remember to move your yarn from back to front as you knit and purl.)  If you are knitting this ribbing flat for a garment, you should be knitting an odd number of stitches, so that when the garment is seamed together the ribbing will appear to be continuous.   If you are knitting in the round, you should always have an even number of stitches.   This ribbing is the most elastic of ribbings.  It tends to look more loosely knit than stockinette stitch, and because it is so elastic, most patterns have you knit your ribbing on needles that are a size or two smaller than the body of the pattern.

Two-By-Two (2×2) Ribbing:

2x2Ribbing

This ribbing is made by K2, P2 across the row.  It is a multiple of 4 stitches, so when knitting a flat piece to be joined with another, you should be knitting a multiple of 4 plus 1 stitch so that the pieces will weave together correctly.  For knitting in the round, you would knit over a multiple of 4 stitches.  This is a popular ribbing and it works well for sock cuffs, but it is not as elastic as the 1×1 ribbing.

Three-By-One (3×1) Ribbing:

3x1Ribbing

This ribbing is also a multiple of 4 stitches:  K3, P1 across.  The rules for 2×2 ribbing also apply to this ribbing.  As you can see in the picture, this produces a wide rib with an almost invisible valley.  I have seen this ribbing used in sock patterns and it does give the socks and attractive looking cuff.

Other Ribbing Patterns: There are many other variations of ribbing, including Cabled Ribbing, Four-By-Two Ribbing, and Six-by-Three Ribbing.   I will include an example of Cabled Ribbing in a latter post on Cable Stitch Patterns.
