How to Tie the Perdigon (Olive)
- 1
Step 1
Slide the slotted tungsten bead onto the jig hook and seat it behind the eye. Secure the hook in the vise.
The slot should face downward on a jig hook for proper seating.
- 2
Step 2
Wrap 6 turns of lead wire behind the bead and push forward to lock the bead in place.
- 3
Step 3
Start white thread behind the bead and wrap a smooth, even foundation down to the hook bend, building a slight taper.
- 4
Step 4
Select 3-5 Coq de León fibers, align tips, and tie them in at the bend. Tail length should equal the hook gape width.
Keep the tail sparse for a slim profile.
- 5
Step 5
Tie in gold Ultra Wire along the side of the shank for ribbing.
- 6
Step 6
Attach olive body material (Body Quill or thread) and wrap a slim, tapered body from tail to bead.
Keep wraps smooth and tight—the slim profile is critical for fast sinking.
- 7
Step 7
Counter-wrap the wire rib in open, evenly spaced turns up to the bead and secure.
- 8
Step 8
Switch to fluorescent fire orange thread and add a small hotspot collar of 3-4 wraps just behind the bead.
- 9
Step 9
Whip finish and cut thread. Apply a thin, even coat of UV resin over the entire body and cure with a UV light.
Rotate the fly while curing to prevent resin from pooling on one side.
