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:

Master Hand KnitterMaster Hand Knitter

2025 was a year of focused effort toward completing the Master Hand Knitter certification program curated by The Knitting Guild Association (TKGA.org). TKGA is a group of highly experienced knitters who work to help others learn and improve their knitting through various correspondence courses, certification programs, online conferences, in-person conferences and online reference materials. They publish an online magazine, Cast On, quarterly. A yearly membership is $35 and is well worth the price – giving you access to a wide range of resources and expertise.
The Master Hand Knitter certification program is a guided mastery learning program. One achieves mastery through a guided self-study process that includes improving various techniques through practice, learning to research and judge your work and applying new skills. You submit your work and it is reviewed by a group of Master Hand Knitters. You receive a written evaluation of your work along with suggestions on how to improve your work where it did not meet their standards for proficiency.

There are three levels in the program:
Level 1 focuses on basic skills such as determining gauge, making increases and decreases, and knitting some basic stitch patterns.
Level 2 focuses on finishing techniques. It covers different cast ons and bind offs and different methods for seaming and finishing.
Level 3 focuses on designing knitwear and pattern writing. Includes work on advanced techniques such as double knitting, entrelac, brioche, slip stitch and mosaic patterns.
Each level includes completing at least one project demonstrating the skills covered in the level.

 

This program is a journey – not a race. But it was, for me, a wonderful learning experience and a proud accomplishment. I achieved my certification as a Master Hand Knitter in August 2025.

Three Stretchy Bind-off’sThree Stretchy Bind-off’s

All of us know the standard bind-off (K2, pass first stitch over, *K1, psso, repeat from * until all stitches are bound off). This is a useful bind-off and it works well for any number of knitting projects where you need a nice firm edge. You can occasionally have trouble with it, however, if you do it too tightly and most of us have experienced the frustration of a too tight bound off edge. Most often to correct this you simply need to bind-off more loosely by pulling your stitches out a little more when doing the passing over of the stitch.

Then, there are those projects where you simply need a much more elastic – or stretchy – bind-off. I discovered a couple of these stretchier bind-offs as I was looking for a different bind-off for my Crazy Zauberball Shawl. And I thought I’d post them here for future reference with some of my notes.
You see, I tried them all in the process of finishing the shawl and ended up doing the standard bind-off anyway because I was at the very end of my yarn and all three of the bind-offs used up more yarn. So, one thing to keep in mind with these more elastic bind-offs is that they are stretchy because they use more yarn.

The Elastic Bind-off
This is a very nice, stretchy bind-off. I will probably use it for toe-up socks and ribbed necklines.

To do the Elastic Bind-off:
Knit first two stitches, then * slip them back onto the left needle.
Then knit these two stitches together through the back loop.
Knit the next stitch and repeat from * until bind off is complete.

Here is a You-Tube video of this bind-off:

The Lace Bind-off
This bind-off is also known as the Decrease Bind-off. It produces a very nice elastic edge that really looked nice on the edge of my shawl, but it takes about 2-3 times more yarn to complete than the standard bind-off. I would use this bind-off with any lace shawls or scarves.

To do the Lace Bind-off:
Knit together the first two stitches on the left needle, through the back loop.
Then slip the stitch now on the right needle back onto the left needle.
Repeat these two steps until the bind-off is complete.

Jeny’s Surprisingly Stretchy Bind-off
Many sock knitters swear by this bind-off. It does produce a super elastic edge, but I don’t think I would use it on a lace shawl.

This bind-off is nicely explained and demonstrated in an article on Knitty.com. Here’s the link:
http://www.knitty.com/ISSUEfall09/FEATjssbo.php

If you haven’t tried any of these bind-offs, I recommend that you do. It’s always nice to have more than one method of finishing off your lovely knitted item. I’d love to hear from any of my readers about any other bind-offs they like/love to use. Just leave me a comment (and a link if you have one). Thanks!

Happy Knitting.

Long Tail Cast OnLong Tail Cast On

The Long-Tail Cast On is one of the most common and popular cast ons. It is an all purpose cast on that gives an attractive and elastic edge and works in almost every type of project. Because of its structure, this cast on creates the first row of your knitting – which is usually considered the wrong side of the work for stockinette stitch.

As the name implies it starts with a long tail – which can be a challenge for a knitter to figure out how long to make the tail before you start making stitches on your needle. A general rule of thumb for this length is 3 times the length you need to form the number of stitches to cast on. Some knitters wrap the yarn around the needle the number of times that equals the number of stitches. I’ve used both methods and both work fairly well.

The cast on starts with a slip stitch (some knitters omit this step). You then form a “slingshot” by holding the needle in your right hand and using the thumb and forefinger of your left hand so that one of the two strands wraps around the thumb and the other wraps around the forefinger, forming a “Y”. The tail strand should go over the thumb and the working yarn should go over the forefinger.

To form a new stitch, put the needle under and into the loop on the thumb, then go over the yarn on the forefinger and bring the strand through the thumb loop. Drop the yarn off the thumb and gently tighten the loop on the needle. Repeat until you have the desired number of stitches.

There are several variations of this cast on. I have included a link for the Alternating Long Tail Cast on, which provides a way to alternate knit and purl stitches for a ribbing and gives a moderately elastic edge.
