Last night I was watching a show called Your Bleeped Up Brain and they kept saying how we see what we expect to see. This is a perfect example. I really thought the video I linked to was the k2, p2 for 2 rows then p2, k2 for 2 rows version. Duh. So my sweater is double moss stitch aka box stitch, as in Claire's link. Thanks, Julie, for clarifying.
Claire, if I post a photo now all I can really show is the stitch pattern. If you are desperate to use it, make a dishcloth. I just used it for one and I think it makes a good one. I chose this pattern because it is cushy and soft and squooshy. This is definitely a sweater for comfort, not so much for style.
