Overview
A 20 piece set of metallic yarn thread sized for tying steelhead flies and nymph bodies, sold in a range of colors under set A. Each strand is nylon, with roughly 80 yards on hand across the pack for building bulk or flash into a fly body.
This is raw tying material rather than a finished fly, so the buyer already ties or is learning to. The metallic finish gives flash without switching to tinsel, and the color range in set A means one purchase covers several patterns instead of one.
- 20 piece metallic yarn set
- Nylon construction
- About 80 yards on hand
- Set A color range
Who it's for
Fly tiers working steelhead and nymph patterns who want a metallic body material in several colors at once. Not for anglers looking for a ready tied fly or for saltwater fly tiers needing UV resistant thread.
Strengths and trade-offs
Drawn from this product's published specifications.
- 20 colors in one purchase
- Metallic flash without extra tinsel
- Enough yardage for many flies
- No shade names beyond set A
- Not built for saltwater UV exposure
Performance notes
Nylon yarn takes dubbing wax and thread wraps the way most synthetic tying yarns do, and the metallic finish reads as flash under water without adding a separate tinsel rib. With 20 pieces in the set, most tiers will get many flies out of one pack before running low on any single color.
