Barr's Graphic Caddis
Tied by Jay Hall
Start by winding thread to bend. Tie in tubing and lash it down a little around the bend. Tie in the Flashabou. Advance the thread back up around bend. Wind about three turns of the flash and tie off. From that point forward build up a thread base to just short of the Eye. You want a reverse taper that is fatter at the bend and tapers toward the eye. Wind the tubing over the flash and thread base to just short of the eye. Take a partridge feather and clip the tip out of it to form a V shaped feather. Tie this in so that the tips extend just past the hook bend. Wrap this down over the front of the tubing, so that you leave about 1/8 inch at the front for a thorax. Tie in a strand of Ostrich Herl and wind it like a hackle to form a collar. Wet you fingers and pull the Herl back a little to make room for a small head. Whip finish.
