I was commissioned to make a brain slug hair clip and beanie for a friend's teenage daughter, but the green I used, (while matching a Google Image search) wasn't the green my friend was looking for, so I made a second set. The 2nd beanie is not as neat, because it needed to be bigger (to fit my friend's big head :P ) and I made it with double crochet instead of single, like the first one. He was very happy with the second batch though.

Hats are basic hats with eyes and antennae, and the small, stuffed slugs are the large slug pattern from Hook & Needles.
