Product Details
We have a limited quantity of this hard-to-find heavy, 4-Cord Coats Barbour Linen Upholstery/Mattress Twine. It is unwaxed in natural, unbleached color and is excellent for extra heavy duty sewing such as weaving straps or stringing necklace beads. Linen is the strongest natural textile fiber, making a superior and long-wearing cord that is historically correct for hand sewing. This is much heavier than even our linen sewing threads. 1/2 pound spools, made in the European Union.
