Cables mixed with such a gorgeous texture? Sign me up! I love this variation on a moss stitch all over the garment but the cable panel really makes it stable out, and it's so satisfying how the ends of each cable lean into the ribbing. This will definitely keep you interested as you knit it and it won't take too long to make, either.
