One of the cheapest and easiest popular DIY hacks is the classic duct tape wallet. We've covered how to do that before, but DIY weblog Craft shows us how to make one that, surprisingly, doesn't look all that bad.
Sure, the duct tape wallet is well-known for being cheap, easy, and supremely awful-looking, but why continue to spend money on plain black wallets that end up going through the washing machine anyways? If you want to take a bit more time and use, say, an X-Acto knife instead of cheap scissors and a ruler to keep things a bit straight, you can come up with something pretty cool, with a bit of individual flair. Craft has got you covered with the full guide, complete with measurements, pictures, and a very functional design. Hit the link to check it out.
