I have been in the market for a new wallet. I wanted something small and cheap. This morning I came across the Paper Wallet via Instructables.com. It took me a few minutes to make it and man this thing is great. It's small enough to carry in your front pocket, will hold 4 easy access credit/id cards, two more cards "locked away," and a lot of cash. Perfect for me since I like to roll with a big wad of cash. Or not. But seriously, this was fun and should work great. My new paper wallet is literally half the size and thickness of my old leather one. There are already some hacks for this on the website from other users. Check it out.
