Helpful 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. “

Stitch Patterns – Seed Stitch, Irish Moss Stitch & Double Moss StitchStitch Patterns – Seed Stitch, Irish Moss Stitch & Double Moss Stitch

These three stitch patterns create an allover textured pattern using a combination of knit and purl stitches. As such, these three textured patterns are great for decorative borders. Between the USA and UK there is some confusion related to the Moss Stitch – I have seen references to the Moss Stitch which are exactly the same as what I know as a Seed Stitch here in the USA.

Seed Stitch (Moss Stitch):
SeedStitch
This is one of my favorite patterns for borders with the stockinette stitch. It lies flat and does not roll or curl. It is reversible and I love it for front bands on cardigan sweaters.
This stitch pattern is a multiple of two and a repeat over two rows. The first row is the same as a 1 X 1 ribbing: K1, P1 across the row. On the following row, all stitches are worked the opposite of the way they face you – i.e. you purl the knit stitches and knit the purl stitches. Seed stitch tends to expand widthwise and is wider than the same number of stockinette stitches.

Irish Moss Stitch:
IrishMossStitch
This stitch has a diagonal texture. It is a multiple of two stitches with a repeat over four rows. The first two rows are knit the same as 1 X 1 Ribbing: K1, P1 across the row. Then the next two rows are knit the opposite: P1, K1 across. You repeat these four rows to make the textured pattern.

Just like the Seed Stitch, the Irish Moss Stitch creates a reversible fabric that lies flat and does not roll or curl. The fabric will tend to expand crosswise and the stitches may “seat” themselves after washing. If you are using this pattern stitch as the main body of your garment, it is best to knit the garment to the actual measurements of the chest of the intended wearer before the first washing.

Double Moss Stitch (Double Seed Stitch, Box Stitch):
DblMossStitc
This stitch pattern is a multiple of four stitches repeated over four rows. The first two rows are the same as 2 X 2 Ribbing: K2, P2 across the row. On the next two rows, you do P2, K2 across. It has essentially the same properties as the Irish Moss Stitch. This pattern is wonderful for knitting textured scarves that do not roll or curl on the edges.

Knitting Needle Sizes & ConfusionKnitting Needle Sizes & Confusion

Knitting Needles sizes are fairly straightforward in the sizes that one uses for DK, worsted weight and bulky yarns. (Size US 4 and up). But it is a much different story when it comes to small diameter needles used to knit fingering, lace and other finer weight yarns. This can be very confusing – I just discovered that there is a significant variation in the sizing labels for some of these needles.

Let’s start with the standard “US” sizing – which uses a numerical designation for knitting needles, from “0000” up to 35 – with the needle diameter increasing as the numerical designation increases. Seems like a fairly straightforward system – until you run across US size 1 & 2 needles that are different diameters. If you never use a knitting needle smaller than US size 4 (which has a diameter of 3.5 mm), this will not be a problem for you. IF, however, you get into knitting socks and lace using much smaller diameter needles – it may cause you to pull out your hair.

Fortunately, most knitting needles sold today also come with their diameter size stated as well as their US size. What I have currently in my assortment of circular knitting needles are as follows: US Size 0 (2.00 mm); US Size 1 (2.25 mm), US Size 1 (2.50 mm), US Size 2 (2.75 mm), US Size 2 (3.00 mm). These needles have all been purchased in the last 10 years. I have seen patterns referencing size 1.5 needles, so I am guessing that the size 2 (2.75 mm) needle may also be a 1.5, but it’s difficult to tell for certain. Just a word of caution to those using patterns calling for these US sizes of needles – make certain your metric diameter matches the pattern (if it’s stated) and BE SURE to check your gauge!

I found two websites that have charts comparing the US sizing to the metric diameter:

Point to remember: Gauge is the measurement of the number of stitches per inch you get with a particular needle – this is more important than using the size of needle stated in a pattern. Always do a swatch for gauge!

Stitch Patterns – Garter Stitch, Stockinette Stitch & Reverse Stockinette StitchStitch Patterns – Garter Stitch, Stockinette Stitch & Reverse Stockinette Stitch

I have decided to blog about various stitch patterns from time to time. So I am starting with the time honored basics: the garter stitch, the stockinette stitch and the reverse stockinette stitch.

This discussion assumes you know how to do a knit stitch and a purl stitch. If you are new to knitting and are not familiar with these two stitches, click on this link: http://www.knittinghelp.com/videos/knit-stitch.

Garter Stitch: this stitch pattern is made by knitting every row, turning your knitting at the end of each row. (You would get the same effect if you purled every row – but most knitters prefer to knit every row). If you want to knit garter stitch “in the round”, you would knit one row and then purl one row – so most patterns using garter stitch are for flat pieces rather than circular knit pieces. The pattern produces a knitted fabric with ridges on each side that is essentially reversible – it looks very much the same on the right side as the wrong side. It takes two rows to make 1 ridge. The garter stitch is great for borders because it will not curl and lays flat once knitted. Many afghan and baby blanket patterns have a garter stitch border and it is often used as the basis for wash clothes and placemats.

Stockinette Stitch: this stitch pattern is the most commonly used knitted fabric. This stitch pattern produces a fabric with flat “V” shaped stitches on the right side and bumpy stitches on the wrong side. It is also known as flat knitting, tricot or jersey knit. Stockinette stitch consists of knitting one row, turning your work and purling one row if you are knitting a flat piece. If you are knitting in the round, you knit every row. Stockinette stitch fabric curls on the edges and at the top and bottom – it makes a good fabric for the body of a garment, but usually requires another stitch pattern for edging and or borders. It also stretches lengthwise when worn.

Reverse Stockinette Stitch: this is exactly what it sounds like – it is simply stockinette stitch fabric used with the purl side as the right side. It has all the properties of the stockinette stitch, but in addition, it will also stretch widthwise. You can see how the 3 stitches differ in the picture below:

If you look at the pictures of my teddy bear baby blanket – you will see how the teddy bear is formed by using the stockinette and reverse stockinette stitches together to form the pattern. This is a good example of how they can be combined to form textured patterning. Aran knitting patterns often combine stockinette, reverse stockinette and garter stitches as part of the textural patterning. Again, here are examples where the stitching is actually very straightforward and easy – but produces a fabric that looks complex because of the wonderful textures.
