I was at the big box home improvement store and discovered a cool way to organize my keychain. I have two keys for different doors and it was a pain in the you-know-what to figure out which key went to which door. My keychain still needs work (don’t ask why there is a paperclip) but I feel better and for a couple of bucks (function justifies this purchase) I can navigate the lock in no time flat. There are some cool websites that have a wider selection.
