This cardigan is worked from the bottom up. The lower body is worked back and forth in one piece to the under arm. For the upper body, the left front, right front & back are worked separately. All edges are worked as you go with no need to pick up stitches. The only place to pick up stitches is for the collar after seaming the shoulders. It is unbuttoned. The first stitch of every row for the edge pattern is always worked in pattern. The first stitch of every row for the main pattern is a slip stitch. Sleeves are worked from the cuff up in rounds to the cap, then worked back forth to shape the cap. The belt and belt loop are worked back forth by using double knitting.
