This remarkably adaptable material looks much like regular chenille but is much denser and of a more uniform diameter. Regular chenille is made from fibers that are spun between two stout threads. It may be unraveled. Ultra chenille is made by raising the nap from a monofilament core. It is all one piece of material and will not unravel. It tapers easily with an open flame. It is the ultimate material from which to construct size #12 and #14 extended body caddis and midge pupa such as Smith's Emergent/Diving Caddis and Palomino Midge Pupa. It also is the best material for tying San Juan Worms and is easily colored with felt markers. 3 yard card.
