Known for its strength, durability, and beautiful sheen, flax linen has been bookbinders’ preferred thread fiber for centuries. Colophon's Best line of linen threads comes boiled and uwaxed, and binders often pair it with natural beeswax for sewing. Spun and plied by Coats Barbour in the EU. See below for available colors and weights.
