I thought about using shadow boxes but I'd have too many holes in my wall from hanging them :) I hate having them in drawers that need to be opened to view so I just hang some from a recycled coat rack as pictured.

I found a nice glass front and sides display case at the thrift store and it's small enough to mount to a wall. (now it sits on a table) It is about 1.5 feet tall 6 inches deep and about 13 inches across. I may get around to rigging something inside so I can have beads dangling from above the inside shelves to use up the empty space.

I also have another idea using a long 6 foot gnarly looking piece of strong oak driftwood.

Good Luck!
