Isn't it just too cute (if I do say so myself)? I used an inexpensive plastic tape measure, size 10 thread (Omega cotton thread in Dark Green Variegated) and a little polyester fiberfill to puff up his shell. I am typing up the pattern, and I hope to get it tested soon. I'll let you know what I decide to do with the pattern once I'm done.
Now I'm off to crochet a little before I have to start some major housecleaning. Wish me luck!
