We spent a good part of a day this week making paper wallets. A short and sweet how-to video is here, presented by a kid. It kills me when he says you will need "a fake or real credit card." I love this one because it doesn't use glue or tape and it fits cards perfectly. It's not so good for cash, which isn't really an issue for me.
We used newsprint for our walltes, which is thin and easy to work with. We stamped it first, with adorable stamps designed by ashely g for AHA. I don't see the exact set we have in the link, but they are all cute.
This cash and credit card wallet was made using this video. We didn't use two sheets of paper, but only one, covering it with packing tape before we folded it. Covering newsprint with packing tape caused some frustration, but it was worth it.
We are studying architecture right now and paper folding, book binding, and sculpture are so intertwined with the study of space— this was a natural fit. Also, the girls have all loved watching this short design video showing simple design projects using everyday objects.
