I just may have created something useful! Okay here we go! Example on Duckling... Pink-Diaper part Purple-Strap (sorry to whoever I took this picture off of) Real Example of finished product I haven't actually tryed it on a duckling yet so I have to wait a few days for mine to get to me, haha. But It looks like it would work great with proper measurements. I'd say I'll make another soon with an adjustable strap and waist. Okay hope I helped! If you want one tell me...I could make it or get you a pattern! Thanks! BTW I'll try to get a good pattern real soon! Thanks again!
