Make an incision, which divides in half the face of a foam parallelepiped.
Insert a CDC feather into the incision.
Keeping together the fibers that come out from the incision, I cut flush with the face of the parallelepiped.
The CDC fibers bundle.
Fix the fibers bundle next to the eye of a grub hook, so as to obtain the wings of the fly.
Keeping the excess of the fibers of the wings slightly in tension, I wrap the tying thread spiral up to the lenght of the extended body.
Go back with the tying thread to the base of the wings ever with open spiral wraps of tying thread.
Go front the wings with the thread and then slightly back to make vertical wings, after I tie the head of the fly.
Trim the fibers that exceed from the extended body, leaving 2 or 3 to imitate the tail of the fly.
Trim the tail excess.
