When you hang dry your clothes, you save on energy costs and you don't wear them out as fast. The down side is that it takes a lot longer for the drying to actually happen. These custom "space hangers" will speed up the process.
When you hang a wet shirt on a normal hanger, or lay it out on a drying rack, the shirt's fabric clings together, making it take longer to dry. As Instructables user flavrt explains, air drying is related to surface area, and these custom hangers double the amount of surface moisture can evaporate off of. All you need to make them is two normal plastic hangers, and a way to space them out and connect them in three points.
In flavrt's guide, plastic tubing and small machine screws are used, but you can get creative. All in all, they shouldn't cost you more than a couple bucks a piece. Hang drying uses less energy, but it can also help you increase the humidity indoors when you're trying to keep warm. Check out the complete guide at the link below.
