I went out and bought a few bags of Hershey mini bars, which I think are being discontinued, btw. I chose them because I thought they would be perfect for coving up with scrapbook paper in the colors that we chose for the party.
I also went to a dollar store nearby, and bought a bag of mini ziploc bags (3"x5" I believe).
1. Open topper, 2. bag with chocolates inside, 3. Rectangular colored cardstock.
It is a bit finicky to hold everyting perfectly still while trying to staple, so after fidgeting with one or two I got smart and held the bag to the cardstock with a bit of double-sided tape.
