Lotta cardigan is knitted from the bottom up.
First, work the rib edge of the back and the front piece separately. Then gather the rib edges and knit the body in stockinette stitch up to the armholes, where the work is divided.
The sleeves are knitted from the bottom up with increases along the underside of the sleeve until full length is reached.
Then gather the body and the sleeves and knit the yoke with raglan decreases all the way up.
The neck opening is formed with short rows.
Then work both front edges up to the neck edge.
