These are little Hershey chocolate nugget boxes. You can make them in all shapes and sizes. I'm sure this could also be done with Timtex and fabric. Hmmm..maybe that's my next experiment. I guess the drawback to making these little chocolate boxes is that you eat the chocolate as you are making it! But, I guess some may say, this isn't a drawback at all.
