Step 2: Base

Find a strong big piece of either cardboard or styrofoam. The paper will be glued onto this.

Step 3: Glue On

Lastly, glue on the pieces of paper nicely onto the base that you are using.
If you want any extra details, some ideas you can put are 2 CDs on the bottom and a strap for your foot on the top.
