I added small eye screws from a picture hanging kit to an antique rubber carriage wheel. The rubber is very hard, but very easy to screw into. I used a saw tooth picture hanging bracket for the back. Just nail it right into the hard rubber.
I also used a chemical called "Novacan Black" to make the bright metal of the eye screws look dark and aged.
I did something a bit differently in another post here,
to display my favorite necklaces with a large antique tricycle wheel.
Hope this inspires you! I love to display my artful collection of earrings. Earrings pictured clockwise from the top are Sacred Cake, Age Before Beauty, Sacred Cake, Fanciful Devices, and Read Between the Lines.
I've even found some for you! just follow these leads by clicking on the photo:
