Ginny’s Cardigan, from The Unofficial Harry Potter Knits
There is an error in the stitch count in the second to last Dec Row under Yoke before the Finishing section. It should say:
Dec row (RS) K1, ssk, knit to m, sl m, work charted patt as established to m, sl m, knit to last 3 sts, k2tog, k1—2 sts dec’d. Work 1 WS row even in patt. Rep last 2 rows 3 more times—20 (26, 30, 36, 40, 45, 51) sts rem each side of m.
