Use Czech faceted beads/Ab crystals, would probably make some eyepins to string it with jump rings in between each. For the hoops, would use 3 different sized embroidery hoops spray painted in a metallic finish.
Use a precut wood plaque for the base (you can find them at any craft store) and screw in a mismatched jumble of painted hooks. Perfect right next to the door for keys, scarves, umbrellas and more. Cute for Maggie's room!
