This is a piece of Stampbord, which you can get at Dick Blick. I used Cranberry Alcohol Ink for the background.
I stamped an older Studio G snowman stamp, this one is a clear stamp, with Staz-On black ink and then used a craft knife to etch the Stampbord. The white parts are just the etched board showing through. I added some Diamond Stickles, because I love them and plan to marry them, and then added a pin back. It's a pretty quick project and now I have a pin for my coat now that Christmas has gone.
Happy Winter, my friends, it's definitely here!
