Step 1: Get your stuff
I chose a white cardboard, but any color will do. You can get creative with what's printed on the cardboard and incorporate it into your design.
> Paper (To make a sketch of what you're going to cut out)
> Frame (To hang your work. If your cardboard is small you can use a photo frame to display it)
> Glue (If you're going to make a cardboard frame)
> Ruler (To make straight cuts)
