Snap-on Window Cover for Boat
Cut Phifertex to the size of the window adding an inch to each side all round. Fold over 1/2-inch hems and sew with V-69 or V-92 thread or finish the raw edges with binding tape. Install snap fasteners at each corner and at 3 foot intervals (or as required) along the length of each side.
