Every now and then I get an email asking for the number, letter or size of a certain crochet hook. I have compiled a list of the crochet hooks I have on hand and the equivalents as noted on the hooks or packaging.
Red Heart Crystalites they are plastic which is not my preferred material but still work well.
The regular hooks I use are by Susan Bates I LOVE THEM! They are straight hooks that don't have a tapered head which allows for smooth stitches that glide easily through the loops without catching or snagging when you are trying to work.
Hope this is a help to some of you:)
