Martha Stewart, bless her heart, has given us instructions to create glass storage and although the act of putting stuff in a jar doesn't exactly require much instruction, her tip for adding a bit of felt to the bottom of the jar is rather cool for a few reasons.
For starters, it makes cleaning easy. Simply remove and shake, replace and forget having to clean the jar. If you're looking for something a little easier, try using rice (which you could dye if you were so inclined) which could simply be tossed out.
In addition to aesthetics, ling your jars helps protect them from sharp objects and likewise, your objects from the jars. It's a fun place to add a little color to a space, but the key to making it look amazing is to simply leave a little space in the jar.
