Kitchen Design Classics - Mason and Ball Jars: Used to store preserves and pickles, these jars are a simple and cheap alternative to Tupperware. Use them to store dry goods, sort kitchen tools, or hold flowers.
One of my favorite things in the universe: blue Ball jars (with original tops of course). You can use them for drinking, just for looks, vases, turn them into solar lamps, use them for desserts. They're awesome!
