I finally made them! Thanks to the free pattern from Julie from Little Cotton Rabbits I now have my very first item of clothing that isn't in garter stitch! The first few lines of double rib were a bit wobbly but I'm pleased with the double moss stitch.
I now have plans to make my own pattern and perhaps sell them in the near future. I ordered some Cashcroft DK in purple and am happily knitting another pair.
I'm off to finish my Debbie Bliss teddy bear...happy sewing!
