Here's a really cool tying video that Tim Flagler made on how he ties the Picket Pin, complete with retro tools and hooks. This is a fairly old pattern that originated in Montana, that still produces well throughout the US of A, for trout and panfish. I know a few anglers that fish it regularly and do quite well: they fish it dead-drift as you would a nymph; swing as you would a wet fly; and also by retrieving it just as you would fish a streamer. The primary material in this pattern is peacock herl, which as any fly fisherman knows, has almost magical properties when it comes to attracting trout. Make sure you watch this with the sound on.
Tie some up, and sharpen your hooks!
