Ok I was trying this hat last night, my first attempt at following a non-Japanese and non-amigurumi crochet pattern and thus trying to remember what all the abbreviations mean etc.
I just have a question about the start, where you go from the little tail to starting to work in the round:
Where is says "In last chain, do 4 sc.", what does that mean? Do you do a chain of 4 stitches or do you do 4 single crochet stitches in that one last chain? I can't work out how they'd all fit if the latter was the case.

I took it as making a chain of 4 stitches up, if you get me, and then according to the nest line of the pattern, did 2 another chain and the did 2 single crochet stitches in each of those 4 chains, and did a slip stitch to join it so it forms the first circle of the hat - is that on the right track?
I'm sorry if that's a very basic question, but I have looked at books and websites etc. on working in the round and can't quite make sense of it in terms of this pattern with the 2 sc in the chains, so thanks if anyone can help me!
