Linen cloth was woven of flax fiber in many grades and weaves. Used in every aspect of living from clothing, to household needs to furnishings to the shroud made for the corpse, linen was so common that a tax was proposed as a source of easy revenue on the coarser sorts being imported into the US towards the end of the 18th century. Woven stripes were a common way of introducing pattern and color into textiles inexpensively. Sometimes the looms were warped with the stripes but likewise you found the stripe introduced in the weft yarns. The color could be introduced with a linen yarn or in the case of many Manchester goods, in a cotton yarn. Samples can be found in several Manchester books dating from the 70's and early 80's. Indigo was a common color found in linen. It was colorfast and could take a hot wash making it a good color choice.
