How to tie it
Mount a standard dry hook and start black thread behind the eye, laying a base to the bend.
Tie in a strand of pearl Flashabou or tinsel and wrap it forward over the shank as a flash underbody, then tie off.
Cut a strip of black foam laminated over white foam, one hook-gap wide.
Tie the foam down at the bend, leaving a short tag over the back, then bind it at the front third — leaving a deliberate gap of bare shank in the middle. That gap is where the hackle goes and is the whole construction.
Tie in a grizzly hackle at the rear of the gap.
Palmer the hackle through the gap in 4-5 turns and tie it off at the front.
Tie in white round rubber legs at each corner of the foam body, two pairs, splayed.
Build a small head, whip finish and cement.
