Over the coarse of a few projects, you can accumulate quite a collection of small screws, nails, and other small parts. There are several ways you can store these items; baby food jars, small paper bags, soup cans, or even a multi-drawer small parts organizer. The trick is to be able to quickly see what is inside each container without having to waste time searching. Using your hot glue gun, attach a sample of the small piece on the outside of the container. This will give you a quick, visual reminder of what's inside.
