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:

The Roomba Ate My Socks!The Roomba Ate My Socks!

Roomba
I have a Roomba – which is a small robotic vacuum cleaner. You are supposed to be able to contain it to a single room using little devices called “lighthouses”. I really like this little guy for frequent vacuuming of my kitchen. So, the other day, I turned it on and left it to run around the kitchen while I did some things in my office.

Well, it escaped the kitchen and headed off into the living room – where my two at a time socks using magic loop project was laying beside my recliner (I’d left them there the night before) …AND…the Roomba ate my socks!

I heard this weird little sound coming from the living room and went to investigate – and there I found the Roomba thrashing about entangled in my 40” circular needle and the yarn from one of the socks. (I was so traumatized that I forgot to take a picture.)

After turning the Roomba off, it took me several minutes to remove the yarn from around the various moving parts and then deal with the fact that the circular needle had somehow ended up wrapped around one of the wheels. Eventually, I succeeded in extricating my circular needle – but it was a close call, as I had begun to consider the possibility of having to cut the cable. (WHEW!) Fortunately – one sock was still on the circular needle. The other, however, was laying in the middle of the floor – off the needle and minus its ball of yarn. I tenderly picked up this wounded creature and set it aside to recover from all the trauma.

I discovered that the lighthouse that should have prevented Roomba from going into the living room wasn’t working (dead batteries). Once I replaced the batteries, the darn little thing worked just fine and stayed in the kitchen where I wanted it to be.

Socks_BackTog
Happy News! – I was able to frog the wounded sock back to a point that I knew where I was in the pattern and then pick up the stitches and reconnect the yarn to the sock as I reknit it back to where it had been before it was attacked by the Roomba. It is now back on the same circular needle with its brother.

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.

Summer Knitting: Dishcloths # 4 – 6Summer Knitting: Dishcloths # 4 – 6

I am now half way through my Summer Knitting project of knitting a dozen dishcloths. Here are the three I have just finished:

Dishcloth #4 – Crocus Buds
Knitted dishcloth in crocus buds pattern
Pattern from the Leisure Arts “Knitting Kitchen Brights Dishcloths” brochure. Yarn: Lion Brand Kitchen Cotton, color Banana. This was an interesting openwork pattern. The “crocus buds” are created by pulling a stitch over the next two stitches on the needle. It is a simple 6 stitch pattern over 4 rows with yarn overs creating the open patterning between the “crocus buds”.

Dishcloth #5 – Elfin Lace
Knitted elfin lace pattern dishcloth
Pattern from Leisure Arts “Knitting Kitchen Brights Dishcloths” brochure. Yarn: Lion Brand Kitchen Cotton, color Natural. Easy lace pattern, that knits up into a nice dishcloth. The Elfin Lace pattern is an eight stitch pattern done over 8 rows.

Dishcloth #6 – Trinity Stitch
Dishcloth knitted using the trinity stitch
Pattern from Leisure Arts “Knitting Kitchen Brights Dishcloths” brochure. Yarn: Lion Brand Kitchen Cotton, color Natural. Lovely textured pattern produced by using the “Trinity Stitch”. I loved knitting this one. The “Trinity Stitch” is a neat textured pattern.
