I tie the tails and abdomen of the fly on a right hook, then tie also a rooster hackle
Over and under the hook, I tie two foam strip.
On the superior strip, I tie a polypropylene yarn.
Pulling the tying thread, the yarn enters the foam strip and gets up.
I wrap the hackle tilted downward.
I tie hackle near the eye of hook and cut excess.
I tie the head of the fly.
Take off the fly from the vise and cut the excesses of the foam strips
I establish the height of wings with a cut.
