It was super easy to make. I popped the lenses out of two pairs of 3D glasses that I had and thought I would get creative. I found some pictures I liked, printed them and traced the lenses onto the pictures so they had the right shape and size. The hardest part was probably fitting the pictures into the glasses without crumpling them. They are of course purely for decoration, as you can't see anything through the paper. :P I especially like them because I can switch the pictures to anything I want whenever I want.
