Re: Foam ideas?
The cupped popper face is actually a pearl sequin shoved on over the hook eye, after you've put the foam head on. The foam head and back side of the sequin needs a light coat of epoxy or something similar to keep the sequin in place. Googly eyes add more flotation than the stick on solid domed type.
You'll also want to make sure you have the 3mm foam for the head. The 2mm would only work for size 6 or smaller.
