The large containers for crystal lite and such are a great holder for crochet hooks and nuts and bolts. The bottle of wine holders that everyone is selling is super for knit needles. By CHEAPERTHANCHEAP
Tooth brush holders from the Dollar Tree is really cool. I also used a clear box that held all of them when I was traveling. The glass case is a real coup, too. I especially like boxes with lids, as you don't have to "tip them out" and risk dropping them.
I like to crochet while traveling and I've found the perfect container for storing my many crochet hooks is in an empty eyeglass case. These cases fit perfectly inside my purse or my car's glove box.
