The intended purpose of ice trays is to make ice, but they also make excellent organizers for jewelry. They work especially well side-by-side in a shallow drawer, or you can stack them.
Here's another jewelry storage idea. A mesh letter tray hung on the wall will hold a LOT of earrings. This one came from Dollar Tree and cost - you guessed it! - just $1.
There are all kinds of shoe organizers on the market. Too bad they're less than useful for sizable goth footwear such as Demonia platform heels or New Rock boots. I use two sizes of wire stacking shelves for my shoes. ClosetMaid vertical organizers are perfect for boots.
Perversely, I’ve used an IKEA shoe rack to hold towels because it was shallow enough to fit the small bathroom space.
It makes a luxurious home for my spools of ribbon.
What kinds of creative storage are you using?
