I bought tiny rubber stamps (used, on eBay,) and a pad of permanent ink. I stamped these tiny roses on the back of one of my glass gems.
I was inspired by a rectangular piece I saw on Pinterest. The inspiration piece used alcohol inks, but the accompanying article also mentioned using Stickles glitter glue. I don’t have alcohol inks, (yet,) but I did buy this 3 pack of Stickles on clearance at Michael’s a couple of weeks ago. Since baby blue AND pink are the 2016 colors of the year, I thought it a wise investment. I think I would’ve liked the gem better in all white. It needs some touch up, too.
