I’ve used this thread for several weeks on my #8 and #10 flies. It ties up smoothly and holds well without fraying. The wax makes it easy to work with, especially when building heads.

Strong and consistent. The 70 denier gives a flat profile that works well with my fly tying routine. No issues with break strength or knot security.

Good thread for small flies. A bit stiffer than some others, but the wax helps with smooth tying. Works well with #10 and #12 patterns.
David Dyer –
Highly recommended for precision tying. The break strength is solid and the thread doesn’t stretch under tension. Great for tying small hooks.
