I use a variety of vintage items to organize and categorize (by length and color) my necklaces.
Tractor belt display racks.
wood bit display rack.
wooden crib part
......and a wicker form looks festive loaded with colorful beads.
I nabbed a couple of these similar, but much smaller, display boards on clearance at Target.
They were meant for use in an office to hold papers and such, but they work perfectly for jewelry.
They hold another collection of brooches.....
.......and keep my earring selection in order.
It would be easy to make your own version of these as well. Use a small bulletin board or picture frame as your base, pad, cover with fabric and add rows of ribbon or bias tape.
