It was so much fun to knit and fast. I did the whole thing in about two hours. The pattern calls for k2tog, but I read that someone said the leaves twirl better if you slip one, knit one and then pass the slipped stitch over, so that's what I did. I don't know if this is actually better than the written pattern, because the original is pretty darn cute too, but it worked beautifully, so I can recommend it.
Since the hat was so quick, I decided to do a pair of socks to go with it. I had the idea to try and incorporate the leaves in the toe of the sock, so after a couple of false starts I ended up with these:
I cast on 32 stitches on a U.S. 5. They are really tight and I think they'll be pretty cosy. I'm not so sure that the leaves really work, but they do look cute together. My first version had the colors reversed, but I decided that it looked too much like an olive!
I didn't even bother with a second one. This will probably end up as a cat toy, since one of my cats really has a thing for baby socks!
I'm pretty sure that the socks will fit, but I am a little uneasy about the hat. Babies heads are always so much larger than they look!
