Basically, this one piece of A4 paper. It's only cut out and glue together, no order piece is added. It's my first time trying this project so I design a simple one. Sadly, I don't know how to draw the template on computer so you will have to draw them yourself (if you want to make them). I will put the measurement on the picture
P.S: sorry if my english is bad.
Step 1: What you need
-Top paper (I choose copper paper)
