Some more interesting etsy stuff I’ve seen:

Removable vinyl wall art by ellynelly – easily customize and decorate walls. You can choose your own colors for most of them. There is also a variety of these created by Blik Surface Graphics, including some designs from Threadless.

Wood and resin jewelry by modica. You can customize these, choosing your own resin colors for each of the wood circles.

“Reflecting pool” earrings by themusesjewels. Most of the blue you see when looking at the earring straight on is being reflected back – it’s really a silvery mirrored dish shape with a blue bead cupped within.
