The Quick Change sewing windows are designed to be used with peel and stick, or water activated, sticky backing. The sticky backing is applied to the underside of the window with the sticky side up. The fabric to be embroidered is pressed down on the sticky side and is held in place during sewing. After the design is complete, just tear away the backing from the window, patch the hole with another piece of peel and stick, and your ready for the next design.
