Appearance
CANVAS, in commerce, a very clear unbleached cloth of hemp, or flax, wove very regularly in little squares. It is used for working tapestry with the needle, by passing the threads of gold, silver, silk, or wool, through the intervals or squares.
Canvas is also a coarse cloth of hemp, unbleached, somewhat clear, which serves to cover womens stays, also to stiffen mens cloaths, and to make some other of their wearing-apparel, &c.
