This is a length of unused poly (might be a blend) material that is woven backed by a thin knit for stability. The backing is not that evil sponge stuff that breaks down into sandy stuff, it's just blue knit bonded directly to the blue plaid weave. The woven top is a plaid of white, mauve blue and a dark blue that is heathered with a little brown. The weave is loose wide yarn weave that has a slightly rough feel like fine suit wool. The material is 54 inches wide and is 3 yards 5 inches (113 inches) and is in very good condition with no problems to note. The back is darker in the pic because of the flash.
