I only have 3 glitters at the moment, and they're 3 I consider absolutely necessary. .015 silver holo, .040 black, .040 fire red. I think .015 fire red would be a must as well, it's next on the list along with Blue, Green, Purple, and Gold in both .015 and .040. I'd like to pick up some .008 glitters in different colors as well at some point. I've used some very small glitters I bought at Target, and they added a very subtle dimension to the baits. Problem is some of them bleed and none of them handle high heat for very long.
