Now you need your fabric. Cut out two squares of each color of fabric (four squares in total) that are at least a few inches larger than the mask pattern. Then place the two pieces of the same fabric together with the wrong side* facing out and the right sides facing inwards.
*All patterned or colored fabrics have a right and wrong side. The right side is more colorful and vibrant: it's the side that is meant to be seen. The wrong side is the underside of the fabric, or the side that was not printed on: it will not be as colorful or vibrant as the other side.
