I've been thinking about methods to cast on for double knitting, and also have looked at cast on methods for double knitting on the internet.
One method I tried was to longtail cast on twice the stitches of the pattern, and then introduce the second color on the first row. I did this method on my pink scarf:
Another method I tried was to longtail cast on with both yarns, treating them as one, and then picking them apart for the doubleknit portion. This example has 2 rows of garter stitch with both yarns treated as one before I picked them apart:
The next method is difficult to explain. I made a slip knot in each yarn, then used the longtail cast on. I put both slip knots on the needle. I cast on one stitch with color 1. I pulled color 2 between the two yarns of color 1 and cast on one stitch. I pulled color 1 around the outside of color 2 and cast on one stitch. Repeated this until I had the required number of stitches on the needle. It was a real pain to do. I wish I had taken a photo of this immediately after cast on, but I didn't. Here is what the cast on looked like after it was knit up.
I found a really sweet caston by Oftroy on YouTube. Oftroy can be found on Ravelry and has a blog called Golden Apples as well as a flickr account.
