Linen warp and woollen weft threads
Linsey-woolsey (also called linsey and lincey) is a fabric made with linen warp and woolen weft threads. It was made between 16th to 19th centuries in England and America. The wool gave the warmth to the fabric. It was popular with the poor. Primarily it was used for clothing including women’s dresses, various undergarments and bed hangings.
Bible forbids Wool and linen mix
Interestingly the Bible forbids this sort of fabric. Deuteronomy 22, Sundry laws, 11: “You shall not wear a material mixed of wool and linen together.”
