I used the Junior Paper Kit by American Crafts, as well as their Jewelry Box silver thickers. The punch is a Martha Stewart border punch, and most of the roughed edges are made by shaped scissors. The stamp is from a Birthday set from OT. I think it turned out pretty cool. It's definitely not what I normally think of for an invite. Now I just have to make about 10 more.
I loved that I could kill two projects with one sketch.
