When I tied that little wire bodied number yesterday, I remarked on avoiding the ‘fat ass’ or bump/hump at the rear of the hook, at the bend, where many materials are tied in. Craig, a helpful commenter, remarked that this can be avoided by tying in materials at the normal point (at the end of the shank approximately above the barb) then wrapping back over the materials up toward the thorax area, which provides a uniform taper and thickness to the abdomen…or, he suggested, using tying thread to raise/form the fly’s shape and thickness and create a uniform shape. Two excellent ideas to avoid that excessive rear end.

Re thread wraps, in the photo, I was using 14/0 thread. A bit unnecessarily small for a size 12 hook; ok, but better suited to smaller hooks. To build up thread wraps or create an underbody, thicker thread can be used, like 8/0, 6/0 or 3/0. The underbody does not have to be the main thread you are using to tie the components onto the shank with.
