We keep a few sizes of crochet hooks available to use for picking up those errant stitches that slip off the needle from time to time. If you need to add some extras to your zipper pouch of knitting accessories, here are the sizes that we recommend:

US Size 1 (2.75mm) Use for lace, sock yarn

US F (3.75 mm) Use for sport/DK, worsted/bulky

US J (6.00mm) Use for worsted/bulky
