Mount the long hook, wrap 15-20 turns of heavy lead, and cover with thread.
Tie in the chenille at the bend, plus a pair of white rubber legs as tails.
Wrap the chenille forward, pausing to figure-8 in a leg pair at midshank and again near the head.
Whip finish. The white legs against the dark body should practically glow.
