I do the same thing with HotShots & Flatfish.
Those little silver blades?.. I leave the flicker blades on, and if a spoon doesn't have one I add one with a small split-ring. Island Outfitters has little brass & copper ones. If you want other colours, just use nailpolish. You can buy sparkle, white, black, worm-pink or glow colours as well as neons. Take your nieces or daughters with you to the make-up counter to "legitimize" your presence or to Claire's for the odd colours.
The guys & gals in the white coats behind the counter are a real hoot to watch when you bring in your salmon roe or rubber worms to get a colour-match.
Another thing you can add instead of the flicker is to tie onto the ring a few strands of crystal flash.
Cheers!
