Londonderry Linen Thread color card with actual thread samples. Numbers refer to catalog stock numbers and the yardage of the spools is also included. This color card comes in a plastic sheet ready to be added to a three-ring binder. Exceptional quality linen thread, wet spun to eliminate "hairs" on the thread. This thread should not be stranded, and has a subtle sheen and luster. Londonderry Linen Thread may be used for cross-stitch, drawn thread, pulled thread, and Hardanger embroidery.
