Label templates on the right sides.
Place the template face down on the wrong side of the fabric and trace around it with a pencil. Pour a amount of liquid fabric starch in a bowl and dilute with half as much water. Cover a portion of your ironing board with an old towel and then a piece of muslin to absorb the extra starch. Place a patch wrong side up on the muslin and paint starch along the pencil line. Center pressing template face down on wrong side of the patch.
