Thanks everyone! It is a lot of fun! Something that was just a few pieces of cardboard and an aluminum can yesterday is a camera today! I'll try to just sand the dimple made by the pin. I sanded the hole after I made it but the hole is probably not perfectly round. I just love the look of pinhole photos. Mine were just extremely fuzzy. I think that I just need to keep it stiller! I already have 2 kids that want to make cameras for a project. Should be fun! We are just using paper so I just need to increase my time that the pinhole is open. Was my first contact print today too! Fun, Fun!
