Randall Kaufmann created Kaufmann’s Stone that has become a standard pattern on imitating large stonefly nymphs. This is one of the many versions I’ve tied inspired by that pattern. I tied and shot this for an article on Pohjolan Perhokalastaja magazine that was about different methods for imitating legs on nymph patterns.
