For those of you who are now intrigued by the stranded knitting thing and holding yarns thing, here's a youtube video demonstrating several ways of how you can handle your yarns when knitting with two colours:
It's rather long, but it also includes some information on how to do colour changes. The maker of this video, Suzanne Bryan, also has instructions on how to catch yarns over long floats:
Also very interesting because she looks at dominant colours and the difference between stitches made with the yarn in the left hand and stitches made with the yarn in the right hand.
(I have made a little documentary video of my learning how to do purl stitching with one yarn held in each hand, by the way. So if you want to see about five minutes' worth of awkward needle movements - let me know!)
