How to tie it
Mount the size 10 jig hook, start light olive thread just behind the jig upright, run a thread base up over the upright to the eye and back.
Tie a pair of medium black bead chain eyes on the flat of the shank, set a little farther back from the eye than you would expect, with tight X-wraps in both directions, then take turns between the eyes and the shank to lock them down.
Run the thread back to the bend and forward again a couple of times to build a base.
Build the body: pull several clumps of light olive Laser Dub, align the fibers by pulling the bundle apart and restacking it, sweep it with a dubbing needle so nothing runs crosswise, then pinch it at the middle and fold both ends together into a neat brush. Bundle it tight and cut the ends off square.
Singe the cut ends with a lighter, pinching and rolling the hot end in your fingers until it forms a neat point. You now have a hollow, tapered loop body. Whisk the lighter around the outside to burn off loose fuzz. Adjust how tightly the loop is pulled to set the body shape.
Tie the burnt point in at the bend so the body extends about a shank length behind the hook, with the folded end running forward; trim the forward ends where they meet the eyes and wrap forward over them, jamming the material up against the back of the eyes so the underbody bulk is already built.
With a brown Sharpie, draw four thin bands all the way around the body, including the underside, since the fly rides point up.
Take one strand of motor oil Perfect Rubber, catch it an inch or two from the end along the far side, stretch the long end back on the near side and lock it with a thread turn so a leg angles out each side of the abdomen; leave them long for now.
Tie in a grizzly hen saddle feather by the tip just behind the eyes and take two or three turns as a soft hackle collar, stroking the fibers back; tie off and trim the stem.
Build a small thread head around and in front of the eyes, whip finish, cement, and trim the legs to length.
