Repair broken jeans, without a machine. Reboot a broken zipper. Make the scratches on wooden furniture disappear. The same goes for photo frames, plates, knickknacks, watches, organizers and toiletries.
Things in the house break from time to time, but a little glue or duct tape can go a long way. Certain items can be repaired fairly easily at a significantly lower cost than buying a replacement. An added benefit of fixing something is that it keeps it out of the landfill for longer.
