Upavon Chadwick's 477 Yarn Substitute

A nearly identical substitute yarn for Chadwick's 477 yarn which is the material for Frank Sawyer's famous Killer Bug. 

Upavon says:

Upavon by name, Avon by nature. Born on the banks of the River Avon we developed this Chadwick's 477 substitute* as close as possible to the original material used by the legendary Frank Sawyer. Traditionally used to tie Sawyer's Killer Bug, the translucent buggy effect makes for an excellent natural-looking material for nymphs, dries and emerger patterns.

- At least 10m per pack

- Presented on a reusable yarn winder
