Folding paper with dirty hands is so much fun. I am sure this is going to be a thing with me. There are several ways that I am considering exploring this process.
Notice that the background has smudges. I did my folding with two pieces of paper. One to fold and one on the table. In the process of folding the paper on the table became smudged. It looks more like a drawing when the two pieces of paper are photographed together.
