Have you ever heard or read something that refers to the "wrong side" or "right side" of crochet and wondered WHAT?? You aren't alone. A lot of people have no idea there is a wrong and right side.
The only time I really notice a difference is in hats, worked in the round, in hdc or dc st. The wrong side looks like train tracks to me, creating parallel lines each round. It may just be me, but the wrong side of these hats also looks duller to me. Not dull, as in boring, but not as "shiny".
Here are some great articles and I hope they help:
My favorite article on this topic is by Planet June.
