I designed these costumes for my kids over 20 years ago. Now, the Turtles are popular again, and my "kids" said I should make and sell them. Pattern sells for $5 at my etsy.com shop, TresChicCrochet. Includes shells with adjustable straps, cap, mask belt, and bands (including knees). Photo shows sweater & pants, but these are not available. Thanks for looking.
