I used the same stitch as comfi cardi from Crochet Me, and the same basic up-and-over method, but made it a bit tighter. I was going to add a bit of ribbing, but then I saw a pic in a magazine of a Moschino crochet cardi (for £1300!!!) with a chiffon edging so thought I'd have a go. Sewing used to be my thing (before I realised crochet took far less time and mess!) so it was quite good to combine the two. Would be interested to hear if anyone else has tried similar things?
