Slide the tungsten jig-bomb bead onto the jig hook, secure it in the vise, and start the pale gray thread behind the bead; lock it in and trim the tag.
Wrap the thread down the shank and back up.
Tie in ice-blue 2-fly wire along the near side, wrap the thread forward past the tie-in, then take clean touching wraps back up to cover the wire.
Wrap the wire forward in evenly spaced open turns for segmentation; secure it behind the bead and helicopter off.
Dub a small, tight noodle of UV gray Ice Dub and wrap a slim thorax behind the bead.
