Do You Know? Swatching 101

This is the first in a series of  blog posts about swatching. It has taken me years to gain an appreciation for swatching and I frequently see posts in Ravelry forums about issues coming from swatches. If you are on Ravelry, you have probably seen them too. There are usually a number from new knitters/beginners that ask why the sweater they just knit according to a pattern doesn’t fit and many times, these knitters either didn’t swatch at all or didn’t knit a proper swatch. So, this set of posts is intended to share what I have learned over the years about swatching.

Take my quiz below to check your understanding of swatches.

Question 1: True or False: A swatch must be 4 inches by 4 inches (10 cm X 10 cm).

Question 2: True or False: The needle size stated in the pattern is the size needle you must use to obtain the pattern’s stitch and row gauge.

Question 3: True or False: Row Gauge is not important.

Question 4: True or False. Swatching is necessary for knitting sweaters and other fitted garments.

Question 5: True or False: You must get gauge when knitting from a pattern.

My next post will cover swatching to obtain gauge. If you have a question about swatching, please post it in the comments. I will try to incorporate an answer in my upcoming posts.

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:

  1. 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.
  2. 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.
  3. 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. “

First pair of SFS Socks Finished!First pair of SFS Socks Finished!

Yesterday, I finished my first pair of regulation socks for Socks for Soldiers, including weaving in the ends.

These are very long socks! I now have them washed and they are currently drying in the dryer. I need to run to the store and pick up a few extra “goodies” to put in the package and write my letter to the soldier who will receive the socks. Then, I should be ready to package everything up and send it off to Sarge at SFS.

Here’s a picture of the finished socks:

Time Out for a TurtleTime Out for a Turtle

Introducing my version of Sheldon the Turtle:

This project was not on my list — but I couldn’t resist!

This toy turtle knits up fairly quickly and makes a very soft, cuddly toy that is about 8 inches long and about 5 inches high. I used the yarn called for in the pattern — Knit Picks Shine Sport, but I changed one of the colors. The original colors are “Grass” and “Green Apple” — the “Green Apple” is the main color. Well, I used “Harbour” for the main color and then used “Green Apple” for the contrasting color. These are the colors my DIL is using for the baby’s room, along with a turtle theme. So now my grandson has a snuggly soft turtle to match. (BTW – he’s scheduled to arrive this Thursday!)


I really like the Knit Picks Shine Sport yarn. It’s a blend of 60% cotton and 40% Modal and it is really soft. I just loved the way it knit up. Shine also comes in a worsted weight yarn — and I’ve ordered some for a couple of other toys I have in my “someday” queue. (I know — the stash grows…)

Yesterday at the knit meetup, I learned that Knit Picks has several patterns for costumes for Sheldon. Since the body and the shell are separate pieces — it’s really easy to change Sheldon’s shell for another outfit… who knew? The patterns are free. There’s also a Sheldon group on Ravelry.
