Ages ago I bought some Jewel Beetle wings - which is kind of gross - but still very very cool. They've been used for hundreds of years to make jewelry and in ... embroidery. They are this insanely beautiful chrome-green colour, and they are hard as heck too. I actually have to drill through them.
Anyway, I keep getting New Ideas as I was making them. There will be 2.... One will be a commission and because I really want these things to come out perfectly, there was nothing to do but take them apart and redrill wings, tinker and tailor and redo them.
