FRONTS
I have widened the fronts to get my size, kept the tiny cabled 2x2 rib, and added another buttonhole (total of 4) and several more rows of ribbing, which will sit at my natural waist (just below the bust).
Right front (left front)
CO 42 +1 for seam allowance
work 4 rows in seed st.
*** from here, all instructions keep a 3-stitch seed stitch border at the right edge, or left for the non-buttonhole side (e.g. - RS row: K, P, K, k to end; WS row: p to last 3, k, p, k). Omit buttonholes on left front; work those rows in the established stitch pattern.

Work even for 30 rows; place sts on holder. *Note: I put a Celtic knot design on the back of mine, starting right after the arm hole shaping -- it should have been a few rows sooner, but what can ya do. If you want a chart, comment and I'll post it, though it may be a copyright violation since I kinda tried to copy it from somewhere.
Finishing: I did a 3-needle bind-off to attach the fronts to the back, and then did a crocheted picot bind-off for the stuff in the middle because it was way small. Sew up seams, weave in ends, block, and add buttons.
