While visiting Texas for Christmas my friend, who works in the NICU, asked me if I'd crochet some striped stocking caps for the babies they had as a surprise for the parents for Christmas. I'd never crocheted hats but looked up a couple of patterns, combined them for simplicity and got to work. They were FAR from perfect but they weren't actually wearing them anywhere except for a picture. They were so tiny that they were pretty quick once I got the hang of it. My mom and I crocheted one afternoon and whipped up 11 of them. My nieces made the braids and pom-poms. I used Simply Soft yarn by Caron (my new fav) and don't think I'll go back. It's SO soft and stays soft. My mom crocheted my son a baby blanket out of it and, five years later, yep...still soft. My Michael's doesn't carry it but Hobby Lobby, JoAnn's and Wal-Mart do.
Don't ask me what pattern I used. Like I said, I tried two different ones and kind of ended up doing my own thing in the end. The ones I tried never would have tapered like this or fit a preemie.
