You have to really appreciate the pun in that name, right? A garment made of crocheted shells, and it’s a garment called a shell. Very clever. I didn’t come up with it. Just sayin’. :-)
This design is made in Rayon Petalspun in a gorgeous hot pink color. I made the size medium here, and used less than 1000 yards. You can find this design in the April 2010 issue of Crochet World magazine.
