I’m not sure this technically qualifies as cables, but it looks like them to me. It uses front post stitches. I held the yarn doubled for this.

I was doing so well about keeping up with this stuff lately, but I don’t remember when I finished this! I know it was finished very quickly, though. I didn’t have to block this one.

I added the Long-stitch Points border from The Harmony Guides: Crochet Edgings & Trims.
