This costume is a crochet small animal turtle pattern. This probably will not fit on an actual, real life turtle. My guinea pigs, Tulip and Buttercup, modeled for this costume and it fit perfectly. You can message me requests for new patterns. I will decide if I will make the request or not. If I make it, I will post it for all to see. If it sells one, I will email the person who requested a free copy of the pattern. Feel free to give it a rating! ;)
