Here I offer the lace and shaping of my Louise cardigan re-imagined slightly shorter with elbow length sleeves and a broad neckline scoop, making for a perfect all-season topper. Wide garter stitch bands that trim its edges create a calming balance for the active diagonal of its lace.  Pieces are knit flat, bottom up, with seaming.
