I gave this pattern a whirl, and it's nice.
You have 7 stitches of seed stitch on each edge, then moving inward, 3 stitches of stockinette, 2 stitches of reverse stockinette, then the center cable pattern which covers 9 stitches. (For a total of 33 stitches.)
There are a couple of ideas I have if you want a little change.
1) Instead of the 3 stockinette stitches you could rib the center stitch.
2) You could do the braided cable over the three stockinette stitches halfway offset from the main cable. I think this one would look especially good.
Happy Knitting :XX: :XX:
