How do you display your bottle caps?

[mgardziella]

I am doing a presentation in a couple weeks on a local bottling company. (I'll post that info later[]) I wanted to show a display of the various crown caps that were used. How do you guys display them? I don't really feel like going out and buying a shadow box. Any ideas? Pictures of your display would be nice. (And fun to look at)
Thanks

Those look nice! Where can I spend my 11 bucks to get one?
