Looms and Stitches

Still hunting down the elusive linen loom width info, but here are some starting points:

The St Louis Shirt - An extant garment from the 13th century, with estimated loom width of 24" (what's that in cm?).
14th Century Sewing and Textile Information - wool being woven on horizontal looms at 81-108". The horizontal loom allowed much wider fabrics to be produced than the warpweighted (upright) loom. Silks seem to be much narrower, but this varied by type of fabric and complexity of design. However, there is evidence for tabby-woven linen fabric with a thread count of approximately 20 threads to the centimetre (both warp and weft).

And more sort-of support for using silk facing around the neckline of linen undergarments.
