Wapsi - Sculpin Wool - Hår Flugbindning
"Tying flies with Sculpin Wool material can yield some fantastic results, especially if you're aiming to mimic the appearance of sculpin fish, which are a favorite meal for many predatory species like trout, bass, and even some saltwater fish.
When Sculpin Wool is applied to the head of a baitfish pattern, the fly can develop a unique side-to-side movement that can trigger strikes."
