How many times has it happened that you’ve found the perfect yarn for your project and then suddenly… its discontinued. Or you found the perfect pattern, but the yarn you want in unavailable *Commence hair pulling sequence*.
Yarn substitution is easier than you think, once you get a handle on the basics.
This article will walk you through how to do so avoiding an unfinished project disaster.
In order to substitute yarn its important to have a firm understanding of yarn weight and length. See our Yarn weight guide.
OK, you’ve read the yarn weight guide, now its time to learn the yarn sub rules:
Rule 1: Match the yarn weight with the original yarn weight, or the weight required for the pattern.
This is probably the most important rule. If a 10ply yarn is required, use a 10ply yarn. Using any other weighted yarn will change the outcome of your project drastically.
Rule 2: Check the Meterage on the label.
Metereage refers to the totally length of the yarn from one end all the way to the other. Meterage can vary dramatically between the same weight. One 8 ply could be a 150g ball and therefore measure 250 meters and another can be a 50g ball and be 150meters. Most patterns or projects will tell you the meterage you require for the project, so make sure you’re aware of what that is and pick the amount of balls required based on that.
Two yarns can both be 8ply, but one may be 220 metres per 100g and another 180 metres per 100g. This difference affects drape, thickness, and how your project behaves.
A difference of 10–15% is usually acceptable.
Rule 3: Fibre matters
Fibre refers to what the yarn is made of, Acrylic, Alpaca, Merino Wool.
Side Note:
-
Wool: Warm, stretchy, forgiving.
-
Acrylic: Easy-care, budget-friendly, great for kids and charity knits.
-
Cotton: Breathable, crisp, no stretch.
-
Bamboo: Soft, drapey, silky.
-
Blends: A balanced mix of qualities.
So, if you’re planning on creating a woollen jumper using a blended fibre be prepared for a different outcome. Remember that some items require particular specifics. Shawls, should drape, dishcloths need durability and baby items should be soft and washable.
Rule 4: Swatch It, Baby.
Create a small Swatch of the yarn first to see what it might feel like. Having a swatch about 10cm by 10cm will give you lots of information about the yarn you’re using. Is can tell you if the fabric is right for you, if it looks and feels good and the most important, if your gauge is correct. Our gauge guide makes it easier to double check the needle size against your swatch.
