They are really pretty - subtle too, unlike some nail art! I guess they are stickers, which I could just about manage. If they were drawn freehand then I have no chance.
I have loads of Special FX stickers that I got from Q years ago - maybe I should dig them out.
Ooh, there's a thought FP. It goes pretty small doesn't it. I have some very thin clear stuff that is for printing stickers. It is very delicate so would work for nails and has a backing which might make it work in a Cameo. Then again, I could use fine scissors and make my own even without the Cameo.
