Got the idea for this from one of the most painful tying videos I've watched

Guy's got skills (although looking at that thumbnail he's not too handy with a hammer), but he could have used help from someone who knows how to edit; 21:32 is way too long.
Anyway, I suck at dubbing so I switched that up and skipped some of the underwing accessories. Haven't used this for caddis yet (next summer), but I've tied it in basic black/dark brown for early stonefly emergence and it's worked well, although it was a cast-iron b..ch to see in flat-light conditions in Feb-Mar.

Mash barb and start thread at 75% point on shank

continue wrapping cdc feather, sweeping barbs back (just like CDC & Elk)
