Designed by well-known UK fly fisherman Paul Mclinden, the Blob was originally designed as a lake fly attractor pattern. While most would try to use this pattern on its own, this fly actually fishes best as the top fly on a two fly setup, with the main point fly on bottom. The Blob acts as an attractor for fish to follow, which then ideally see the point fly behind it and hit it. It also makes a killer daphnia fly for those who suffer from the pain of experiencing daphnia on lakes they fish.
