I made 20 treat boxes out of the 3.5 x 4" cutting file from the Craft Room Library. I filled them with small candies (Tootsie Rolls, Tootsie Rolls Flavors, Smarties, and Starburst). I got 10 pieces of candy in each box. I was able to get two cut files on one sheet of 12" cardstock. I made these assembly-line style, so they were pretty quick to do. To glue the side flaps together, I used Aileen's Tacky Glue and then pressed them in a thick book for a while. These are for a family gathering to celebrate my stepson's birthday.
