Slide a bead to the eye if using, then wrap 8-10 turns of lead-free wire behind it for weight and jam it against the bead.
Tie in a marabou tail about one shank length long at the bend.
Split 4-6 strands of flash and tie a few down each side of the tail, then fold the excess back and bind it so fish teeth can't pull it free.
Tie in a saddle hackle by the tip and a length of chenille at the bend.
Wrap the chenille forward to just behind the bead to form the body.
Palmer the hackle forward through the body in 5-6 open evenly spaced turns and secure behind the bead. Optionally counter-wrap wire to reinforce the hackle.
