This picture above is the only part I didn’t make a template for. This is the back. You can use a box that is premade if you can find one that fits. I cut a square the was 2 inches wider than the opening. I then cut 2 inch squares out of all 4 corners. I folded all the flaps and taped them to form a box. This will be taped to the back of the Santa picture.
Don’t cut the inside off. Cut it so it can be folded into the box and taped. It helps to be more sturdy. Although it wouldn’t really effect it if you did cut it off I suppose.
