Start by cutting your colored paper into a 6-inch-by-6-inch diamond. Fold the bottom up to form a triangle with the large base at the bottom. Fold each side up to the top to form a diamond, then fold the sides back down to see the creases. Fold one piece down from the top so the point meets the bottom of the base. Fold the sides back up and tuck them into the pocket. Decorate with markers, stickers or other paper.
