Since I started crocheting, I've actually had to restrain myself from making a zillion nerd and/or cute animal themed baby hats for my nephew who just turned one. I did have to make one though. I mean really, I only have so much self-control.
I made this hat using Caron Simply Soft in Pistachio and a size H (5.0 mm) hook. The pattern is the Yoda Baby Hat from the Happy Hooker blog. I did make one small alteration to the pattern in that I did a whip stitch around the outside edges of the ears, then pulled it tight to give them a little curl.
Overall, I'm really pleased with my very first crocheted hat, though I haven't quite mastered the trick of fastening off things worked in the round and leaving a perfectly smooth edge.
