SemperFli Fluro Brite
SemperFli Fluro Brite, Since Joseph Keen's book - Fluorescent Flies (1964) and Thomas Clegg's book - The Truth About Fluorescents (1967) fly tyers have been working with fluorescent materials. We decided to make a fluorescent thread with advantages that it could be used as a tying thread or as a floss, could be untwisted with the bobbin and used as a floss.
