I used the Halloween popcorn boxes from the Silhouette Online Store. I turned the boxes diagonally to cut the largest one I could on a 12×12 mat. Each one held a ton of goodies (a small Play-doh, 2 pencils, a sticker sheet, a stamp, a small bag of M&Ms, a Tootsie Pop, a bag of Goldfish and a bag of Pretzels, and a Harry Potter Chocolate Frog.)
