Using one of my favorite materials, free cardboard, I will show you how to make an eyeball with a melon baller tool. Eyeballs can be used in many paper sculpture projects, including masks, dragons, lizards, frogs, and so on. I came up with this technique, but you could also make the eyeballs out of paper mache.
Step 1: Get A Small Piece Of Cardboard
Cardboard is everywhere, just grab a piece of one ply cardboard, and you are ready to craft. Tools/materials needed: scissors, melon baller, glue, cardboard, acrylic paint/varnish.
