These 19th Century linen towels are quite fabulous. They are a fairly coarse weave and in all likelihood homespun and hand loomed. I don't think they have been used much, if at all, they still have that beautiful cafe au lait colour of linen. As you can see from the last photograph, linen does get lighter. The more often you wash it, the lighter it gets.
The towels are monogrammed in red cross stitch, Y L, but if that doesn't suit you, then the monogram can be removed quite easily.
