Body Semperfli Quickdub, black mottled (shank length)
Weave Semperfli wire, purple and ocean blue (1 strand of each)
Collar Semperfli Ice Dub, red (2 small pinches)
Second hot spot Yellow tying thread (20-30 wraps)
Cement Loon thin UV resin (1 drop)
How to tie it
Slide a gritty tungsten bead onto a Stealth C12 and start yellow Nano Silk. Build a slight taper the long way round: down the shank, back up, down past where you stopped before, a touch into the bend, and back.
Tie the purple wire in on the side of the shank rather than the top, tucking its tip up into the tungsten bead. Keep it on that side as you bind back down into the bend.
Tie the ocean blue wire in on the opposite side and bind it back to the same point. Pull gently on both as you wrap and they stay one to a side.
Tie in Quickdub up near the bead and bind it down the shank to where the wires end, adding a little bulk, then bring the thread up. Whip finish and cut the thread away completely. During the weave it only gets in the way.
Wrap the Quickdub body forward with touching wraps using the rotary function. Do not bother preening the fibres back; they get pulled out of the weave with Velcro at the end.
With no thread on the fly, lock the Quickdub with a half hitch thrown over the bead end and pull it tight, then cut it off. Break it off carefully or you can lose the knot and start again.
Turn the hook point up and swing the vice to face you. The weave itself is simple: purple over and around the blue, blue under, purple back over, and repeat. Keep the darker wire on the inside so you can read whether the weave is sitting even.
Keep tension on the standing wire while you pull the other one through. Let it go slack and the weave walks round to the back of the hook. Watch the blue dots down each side; even dots mean an even weave.
Work the weave all the way to the bead, then wrap one wire once round the shank one way and the other the opposite way. It is wire, so that holds it while you get thread back on.
Restart the thread behind the bead, wrapping in front and behind each wire in turn and cranking down hard. What you are really anchoring is the whole woven body. Flush-cut both tags.
Dub red Ice Dub onto the thread. It goes on without wax, and build a collar behind the bead, sinking the first wraps into the gap and adding a second pinch more loosely on top. Preen the fibres back.
In front of that, build a second hot spot in bare yellow thread. It takes twenty or thirty wraps to lay down a clean yellow band.
Single whip finish, then a drop of Loon thin resin on top, worked over and left a second before curing for ten to twenty seconds.
Brush the whole fly hard from both sides with Velcro, including the collar, to drag the Quickdub fibres out from under the wire weave. The wire is holding everything together, so you can be aggressive.
