I've been working on various crochet projects and more times than not, get a goin on one w/one size crochet hook and start up another project with a different size hook. Needless to say, I forget which size hook I was using when I go back to work on a project. Does anyone have or know of a way to tell which size crochet hook was used on an item? I usually put the hook I was using right in the project, but sometimes I need that size for another project.
