Bag of Marshmallows: One year, I went as a bag of marshmallows. I took some clear plastic tarp and cut four pieces the same size, about the size of my body, but shorter. Then I painted it to look like a bag of marshmallows, Kraft Marshmallows work best because they are easily recognizable. Then I filled the top two and bottom two layers with blown up white balloons and used clear packaging tape to keep it all together. I wore white underneath. Everyone thought it was a great idea, and it only cost me about $15.00. Thanks to Andrea for this very unique and clever idea!!!
