Place the nymph head in the hook, and make a base of fine thread to lock the it.
Tie and withdraw the thread. Add some cianoacrylate on the thread base and slide the head where it will remain, setting the eyes correctly. Place the lead wire with tight turns. One tip to get a fine beginning of the abdomen: press the lead a bit before wrapping it so it´s thinner and finer at the tip.
With the thick flat thread, white color, cover the lead as you tie the monofilament for the ribbing. Two turns of white thread should be enough. Try not to thicken too much the abdomen, then cover with transparent lacquer to seal the lead that would make the fly rusty instead.
Tie the olive Krystal hackle and shape the abdomen combing the fibers towards the back.
Change to the fine dark thread, tying the strap that will make the back towards the front and also the Krystal Hackle with which we will make the thorax and the legs.
Wrap the thorax and tie it right next to the head, leaving the thread there. Lower the strap of Skinny Skin or PVC with your hand, putting some pressure so it covers the dorsal section with no wrinkles. Make the ribbing with the monofilament to hold the back and shape the sections. Once you reach the head, hold the monofilament with the thread first. The monofilament should point towards the front and then to the back so it attaches everything correctly. Trim neatly. Leave just a tip at the View more...
Finish the nymph applying some cianoacrylate on the thread and painting the upper section of the thorax segments with black permanent marker.
