I did this a couple of weeks ago, but am just now getting around to showing it. :)
All I did was take a 12x12 sheet of autumn colored paper, tear pieces off, and mod podge'd them to the mini pumpkin from Walmart. I put a coat of mod podge over the top to seal it. It turned out pretty nicely. I went a little crazy and mod podged a flat wooden jack o lantern, too. :P
