This cardigan is made up of 5 separate panels: 1 back panel, 2 front panels, and 2 sleeve panels. Each panel is constructed 'sideways' meaning that the first row determines the length of the panel, and each additional row makes the panel wider. The 2 sleeve panels are identical but the 2 front panels are worked differently to ensure that they are symmetrical. The 5 panels are then sewn together to form the body of the cardigan and a button band is crocheted along the edge of the cardigan.
