I modified the yoke motif to add additional rows so that the yoke would be deeper. I used a modification of Chart C to add rows 34 to 47 to Chart B and then completed with rows 34 to 39 of Chart B.

I also modified the numbers with a cast of of 96 sts (though this is still not tight enough; I could have gone with 10-12 fewer at least for a tighter fitting neck).
I also added some short rows before starting the colourwork. I did 1 short row 12 sts from CB, then an increase round of k2 m1. I then worked the increase in the pattern (to 144 sts). After knitting 2 rows, I worked 2 sets of short rows (26sts and 36sts. Then I worked 1 row and then an increase row: k12, m1, k24 (6 increased) and worked 1 row.

Before starting the colourwork, I went to a stitch count of 150 so there were 25 repeats.

For the yoke separation, s=61, f=85, b=93, ua=6.

I worked the body to 9” (190 sts) and then did 4 sets of short rows in the back. 12 sts into the front of the side seam, side seam, 10 sts towards CB, and then 8 more sts towards the CB. I then decreased in the first round of the ribbing (3mm needles) (16 decreased: work 10, dec1 – 7 times, then work 9, dec1 and repeat), working 20 rows of ribbing followed by Jeny’s stretchy cast off.

For the sleeves (66sts), i worked 5” without decreases and then worked paired decreases every sixth row (k1, k2tog, k to 3 before end, ssk, k1) (12 sets total); then work 3 rows. In the first row of the ribbing, I decreased down to 36sts and used 3mm needles. I worked 13 rows of k1p1 ribbing and used Jeny’s stretchy cast off.
