[COLOR=DarkOrchid][SIZE=3][FONT=Comic Sans MS]When do your initial chain, look at it. On one side is nice V and the other side has a bump. Work your first row in the bump and it leaves the nice V as your edge. (This is what I use when doing a crochet provisional cast on. Chain the number I need for the CO, and pick up sts on the bump for my first row of knitting. When I need to take it out, I just grab the end and "unzip" it.)
Other suggestions of using a bit larger hook for initial chain and practice, practice, practice are good ones, too.
