HOOK: #8-18 Tiemco 100SPBL.
THREAD: Red, yellow, or green 70-denier UTC.
TAIL: Moose hock.
WING: Yearling elk hair.
HUMP: Yearling elk hair.
UNDERBODY: Tying thread.
HACKLE: Brown and grizzly rooster hackle.
Humpy Step 1
Start the thread at the midpoint on the shank and wrap a single-layer thread base back to the bend. Cut, clean, and stack a small clump of moose or elk hock hair. Measure this clump of hair to one shank length long. Tie the hair in at the bend. Wrap forward over the butt ends to the midpoint on the shank, and clip the butt ends.
Humpy Step 2
Wrap the thread all the way up to the hook eye, forming a smooth single-layer thread base. Return the thread to the 75-percent point. Cut, clean, and stack a generous clump of yearling elk hair. Measure the hair tips so they are equal to one shank length long.
Humpy Step 3
Place the base of this clump of elk hair at the 75-percent point so the tips extend forward one shank length. Make two taut wraps around the hair.
Humpy Step 4
Pull the bobbin toward you to tighten the first two thread wraps and flare the hair in place on the top of the shank.
Humpy Step 5
Form a tight band of thread to anchor the hair tips. Separate the top half of the butt ends of the hair. Reach in with the tips of your scissors and clip out the top half of this hair as close to the shank as possible.
Humpy Step 6
Hold the remaining butt ends of the hair taut and above the hook shank and wrap back over them with spiraling wraps all the way back to the base of the tail.
Humpy Step 7
Return the thread to the back edge of the wing clump. Lift the elk-hair tips up and back to sweep the wing fibers back along the hook shank. Bring the thread to the immediate front edge of the wing and build a thread dam to prop the hair upright on the shank.
Humpy Step 8
Divide the hair tips into two equal bunches. Bring the thread to the back edge of the wing. Make five or six wraps diagonally through the center of the two wings bunches, from the back near side of the shank to the front far side. Make an anchor wrap of thread around the hook shank behind the wings and then make five or six more tight diagonal wraps from the front near side of the wings to the back far side and make an anchor wrap around the shank at the back edge of the wings.
Humpy Step 9
Post the base of the far wing by wrapping from the bottom of the hair up about an eye length and back down again. This post wrap should bundle the hair into a nice even clump. Make an anchor wrap around the shank before posting the near wing.
Humpy Step 10
Wrap back over the elk-hair underbody to form a smooth thread base from the tail to the 60-percent point on the shank.
Humpy Step 11
Pull the butt ends of the elk hair forward over the top of the hook shank and up to the base of the wings. Hold the butt ends in your thread hand and give them about a half twist to keep them bundled neatly together. Hold the hair taut above the hook and bring the thread up and over the hair, but do not let the thread pull the hair down to the shank yet. Make a second turn over the hair at the same point. Now, pull the bobbin straight down to secure the hair on the top (dead center) of the hook shank.
Humpy Step 12
Clip the remaining butt ends as close to the shank as possible. Use the thread to cover the remaining stub ends of the hump, forming a smooth thread base for the hackle.
Humpy Step 13
Size, select, and prepare one brown and one grizzly rooster feather. Strip the butt ends of both feathers so there is a half shank length of bare stem. Tie these two feathers in at the same time at the front edge of the hair hump with the insides of the feathers facing toward the hook shank. Wrap forward over the butt ends of the feathers to the back edge of the wing and continue wrapping forward over the feather butts all the way to the hook eye.
Humpy Step 14
Wrapping both feathers at the same time, make three or four tight turns of hackle forward from the front edge of the body to the back edge of the wings. Cross to the front of the wings on the underside of the hook shank and wrap both feathers two or three more turns to the hook eye and tie them off with two firm thread wraps. Clip the excess hackle tips flush against the hook. Build a smooth thread head to cover the stub ends of the hackle and whip-finish.
