Schlappen are long heavily webbed
hackles from the base of the rooster
saddle. Schlappen is ideal for collars
on steelhead and salmon flies. It can
also be used for tails, legs, palmered
hackle, spey hackle, beards, throats
and wings. The softer Schlappen
feather fibers move easily in the water.
When wrapped as a collar, they flow back naturally over
the fly.These make great craft feathers.
