I love the large cable in this sweater, so when I designed the smaller cable, I took it from the center portion of the larger cable. I added the rice stitch panels for contrast and to frame the cables. I love the results!
The yarn I used works up at a gauge of 4.5 sts per inch in Stockinette stitch; if you wish to use a different yarn, make sure you find one that will match this gauge.
26 sts and 26 rows = 4" (10 cm) over Tramline Cable, using larger needles
