Stiffy 1650 is a 1.5 oz. multi-purpose, soft hand, medium weight tear-away backing that tears easily and cleanly. It is best used on canton fleece, heavy denim, canvas, corduroy, cotton twill, hats, lingerie, silk, sheets, t-shirts, towels and robes. It is available in white and black. Tear-away backings should be used on woven materials that have little stretch and don't need much stabilization.
