Help with booties
I am a newbie at crochet and trying to make some quick booties. The pattern ("The Quickest Booties in the West" from Pattern a day Crochet calender 2008 - July 14th) says:
Row 1: 5 dc in 3rd ch from hook. Dc in each stitch across. 5 dc in end st. Working in free loops of beginning ch, dc in each loop across. Join w/sl st to top of beginning dc."
So as I understand it the best way to increase at the beginning of a row is to make a longer turning chain, so would that mean I just make a longer chain instead of 18, right? I was thinking 23. Is that correst?
Secondly, I am very confused about the "Working in free loops of beginning ch, dc in each loop across. Join w/sl st to top of beginning dc." Am I crocheting in the round?
Thanks a lot
