I wanted the top edge of their wings 'stuffed', but stuffing something so tiny would have been very difficult, so I layered some thin batting along the top edges. Then after stitching, turning, and top-stitching, the wings had a 'stuffed' upper edge...
I was going to use Apoxie to sculpt the fingers since it's very strong, but it's very soft and not the easiest to work with, so I just sculpted the thumbs and middle fingers first, and let those cure.
