Hi Maggie m!
I'll have to make some assumptions about what you want to display. I'll guess beaded necklaces and earrings with a price range that tops out at 29.99.
These should be *somewhat* safe to display when your customers can touch them rather than behind glass.
Are your earrings on french hooks? Do you want to use cards to keep pairs together? Sections of windo screening or slats set in frames make good earring racks if not on cards. Drift wood, modified stumps, modified branches all can be used for interesting necklace displays.
Or....
We can sell you kinda boring earring cards and clip card rotators to display your earrings and black flocked necklace displays for the necklaces.
Too many options that depend on what kind of products you are selling. Give us a little more info and let us know if these ideas would work for you.
