I recently bought blanks from "lake erie walleye candy" but the site Wakina mentioned seems to have better prices. Thanks for sharing Wakina!
I have yet to fish with them, but I have been painting spoons / blades with fingernail polish and they look really nice. A glitter clear coat over each painted blade really turns the colors on. I plan on having my spare blank blades and paint collection with me on the water so that if a color gets hot I can make up some new ones in less that a half hour or so.
