Casement cloth is a simple plain weave fabric traditionally used in curtains, behind a more decorative fabric.This midweight cloth is specially woven with a heavier cotton warp and weft, and is woven fairly loose and sewn loomstate. It is shrunk during dyeing, tightening up the fabric and pulling it into a dense, sturdy substance.

Herdwick Check Cotton Casement has individual ends (warp yarns) and picks (weft yarns) of natural undyed grey Herdwick wool from sheep raised in the UK.These are fed in to the loom manually during weaving, forming a windowpane check. As the wool yarn shows dyes less clearly than the cotton ground, dyed garments retain the speck- led character of the Herdwick wool.
