Nice SBS tutorial here on assembling a winged wet fly and the reverse wrapped hackled body with the ribbing material securing the hackle. The technique of wrapping the hackle front to back and wrapping the ribbing forward over the hackle to bind it down has been used in the Elk Hair Caddis. Most often the the hackle is wrapped rear to front, but her is another option at Flytiers.Pl
