How do you substitute yarn in a crochet pattern?
Crochet is more sensitive to yarn thickness – here is how to find a yarn that works.
Start with the crochet tension
Crochet patterns often specify tension in trebles or double crochet stitches per 10 cm. Match it with a tension swatch, not just the yarn label.
Consider the fibre
Cotton gives structure and stitch definition, while wool gives elasticity. A wool bag stretches more than the same bag in cotton.
Check the quantity in metres
Crochet usually uses more yarn than knitting. Recalculate the quantity in metres when substituting yarn, and consider buying an extra ball.
