I bought a bag of these at a yard sale years ago and finally got to glitter them up.
The glitter was ultra fine (actually was a fall clearance bundle also on clearance years ago.) Mod Podge Matte the outside and not the cap. Added green hook wires and hot glued ribbon around the wire and cap. Final step to keep glitter sealed in (before adding ribbon) was a clear spray sealer.
Thought about what else it needed so punched out a saying and hung it off the wire. Now to package up for craft fair!
