Any food that comes in a box will do. Cereal, oatmeal, mac-n-cheese, hamburger helper, rice-a-roni, butter. You get the idea. Even plastic like milk, juice, butter bowl lids, sour cream. When ever you go to throw something away (other than wet things like coffee grounds save them for your plants) stop and think for a minute Can this be cut for a template. Cut the box so you have flat pieces. Glue or tape a picture of the pattern you want on it and cut. Real easy.
