Londonderry Lacing Thread

Londonderry Lacing Thread

$7.75

This is the heaviest Londonderry flax linen thread that Colophon sells. Though comparable in thickness and strength to 12/3 Colophon’s Best, this softer 5-ply thread causes less swelling (allows for greater compression) during sewing. Great for any sewing application where extra strength is needed. Sold unwaxed in 70-meter spools. Available in Ash Gray, Beige, White, and Ivory.
