Londonderry Linen Thread is produced from wet-spun, line linen. Unique and unusual is the availability of 5 different weights in a range of colors. Can be used on linen fabric for embroidery and counted thread work. Also, canvas work and hand quilting.
This thread has 3 plies, which should not be separated. Used for embroidery (particularly Hardanger), lace-making and book binding. 50/3 is the thickest to 100/3 which is the thinnest.
