I created this clam as a prototype. We go to the beach a lot in the summer and my husband goes clamming, bringing home a big bucket of clams each time. My daughter requested a plush clam with a zipper for her birthday. After much searching, I couldn't find one that I could just buy. Therefore, I decided to first create a basic plush clam in order to visualize how the zipper would come into play. Even though the zippered one was the reason for this prototype, this clam has become the most popular. If you are curious, this is the one with the zipper: http://courtneydarling.com/#clamzipper BASIC SKILLS NECESSARY Straight, zig-zag and ladder stitch SIZING / FINISHED MEASUREMENTS 5"
