What size is a 9mm crochet hook?

Hook Size: 9mm (Size M-13)

What happens if I use a larger crochet hook?

What Happens If You Use a Bigger Hook? If you use a bigger hook than the pattern calls for, the finished item will turn out bigger. Your stitches may be looser, which can cause gaps to appear in the fabric. This may not be a big deal if you’re making a blanket, but it can be a big deal if you’re making a sweater.16 juil. 2020
