The background is Old Paper and Tumbled Glass Distress Stains, my current favourite pair for a nice translucent base.
The stamp is from a Kaisercraft set called Confidence. The words are stamped using Adirondack Earthtones dye ink in Bottle, Denim and Red Pepper and embossed with Ranger holographic embossing powder. A quick spritz of Sheer Shimmmer (frost) and the twinchie is done.
Its a bit more sparkly than the photo in real life and I think it has a sort of graffiti look to it, at least that was the idea.
