DIY: Hanging jar lanterns. The page gives you a link for the chained lid hangers pre made. I say use an awl and put your own holes in the lids then run chain or whatever works through the holes. This page has several mason jar crafts. Brilliant really.
Mason Jar Storage Shelf | Crafts and DIY Community -- Love this idea! P.S. My dad did something similar in the garage, and it works great for all those little pieces (e.g., nuts , bots, screws, wire caps).
