Beetle wing earrings and baroque pearls.
I found these wings on ebay and have been trying to decide how to use them. I decided earrings were a good start. I just used a small piercing tool to make the hole. Be careful not to apply too much pressure if you do this, the wing will crack if you try to force it.
As for the pearls, again a random ebay find. They are baroque which basically means they are off shaped. I used EC600 glue with some bead caps, it will glue anything together. Even glass. So don’t let it drip on your work bench between the finding or you will have a bead and pearl attached to your desk.
