“Flat” style thread from Veevus. This thread is 2x stronger than most other threads of the same diameter. Very nice for creating slim bodies on midges, and nymphs.
Our sizing recommendation is as follows:
10/0 thread- Ties well in sizes #14 - #18
12/0 thread- Ties well in sizes #18- #22
14/0 thread- Ties well in sizes #22 - #30
