I adapted this to be long-sleeved by casting on 30 for the wrist cuff and proceeding as ordered, increasing 2 every 6 rows, till the sleeve measured 20”. The sweater was huge; I should’ve made a small. I sewed the seams together on the sewing machine with a narrow zig-zag stitch, then serged off the seam allowances since I took it in so much. Bottom pic is as knitted before I took deeper seam allowances, and it’s not blocked yet - gasp!
