Anatomy of a sheet

While waiting to have another fitting for James's doublet I finally got around to doing something with my 3 19th century linen sheets. They were purchased from a cute little French shop in Aubeterre sur Dronne for about 25 euros each.

The sheets had been in storage for about 15 years and had some rust spots most of which disappeared after being boiled washed with washing soda twice.

The sheet was made from two lengths of fabric both 41 inches wide and 3 yards 6 inches long. 45 warp threads to the inch.(last picture)
The two lengths were whip stitched together with tiny stitches approximately 1/6th inch long and pressed open.(picture 5)
The hems were machine sewn (picture 2)
The sheets were embroidered with  2 letters which look like M and C. (picture 1)
