The silk thread performs well in tying salmon patterns. It holds its shape when untwisted and matches the color references in the guide exactly. Great for detailed fly construction.

I’ve used this thread for North Country patterns and it holds up well in the water. The flat lay after untwisting makes it easy to work with during tying sessions.

The thread is consistent in color and texture. A bit more expensive than other options, but the quality and accuracy in color matching justify the price.
