I have for years kept my jump rings in pill bottles - white-out the
top, write gauge and ID w/ Sharpie (color coded to type of metal).
Found a spice rack at Goodwill, bolted to wall, holds bottles
horizontal so lids visible. When low, bottle stored backwards, when
I get so many of them like that I cut a bunch of rings.
Bottle is super portable, shatter proof for trips or Dr. appts.,
grab 2 pliers and a bottle of rings, and I'm entertained for hours
Also liked the Ganoksin tip about tall skinny ice cube trays for
organizing needle files - very cool.
