Senyo's Laser Yarn Dubbing is cool stuff. Use it to form the bulk of heads and bodies on your streamer patterns. Senyo's Laser Yarn is great on streamers for trout, bass, pike, and steelhead. Laser yarn can be applied by dubbing loop, or we like to clump dub it to form heads on our favorite streamer patterns. Works great on baitfish, sculpin, and salmon patterns.
