Fuji Ultra Poly rod wrapping thread in Dark Brown #012 (Size A 100m spool)
Fuji ultra poly rod wrapping thread lays down flat, has no fuzzies, packs well, and the finished color has a deep luster that looks great.
Dark Brown thread, for me at least, is the new black. You can wrap it as the main color or frame a lighter color with it. Either way it offers a subtle depth that looks great on both dark and light blanks.
