They say there are no mistakes in Art, just opportunities. When I was working on this piece I made a terrible mistake, I put some gel medium on the base of the stamped image and then sprinkled it with mica flakes and covered it with gloss gel medium. After it dried it looked like a seagull had done a sparkly poo!
This is done in the very cheap art journal I rejected but decided I'd use to mop up spills. (A4 size)
