These are based on a pair of crab pajama bottoms I purchased at Target. Being a marylander, I love crabs, and even though it's September and not really summer anymore, I just had to do this print.
The colors I used are:
To create the little crabbies, I painted a football shape, added four legs coming off of each side, three pointing down and one facing up, then I added the claws.
