Step #3: Cutting the Interfacing
You can get the pre-shrink fusible material if required. In a similar manner mentioned above, make a frame out of cardboard sheet, but the frame this time should be 2 inches larger so it will be 17 by 17 inches. Place the frame on fusing, mark the 17 by 17 inches size and cut out the square pieces of the fusing using a rotary cutter.
