The Klara cardigan is worked top down with raglan increases. First, the neck is worked in ribbing. The work is then divided using stitch markers, and knitting continues back and forth with increases for the sleeves, front, and back. When all increases are complete, the work is divided into three sections, and the sleeves and body are finished separately. Both the sleeves and the body are finished with ribbing. Finally, buttonholes are worked along the front edge, and buttons are sewn along the edge of the other front.
