Sure, it is double knit and then felted.
Lisa, for this pattern you cast on 84 stitches with the main color, and then in the second row, you add the CC. I used navy for my MC, and when I joined the pink ont he second row, I just tied a slip knot and fed the tail of the navy through the slip knit and pulled tight. Then, you just K1 MC, move BOTH yarns to front, P1 with CC, move both yarns to back, and continue. On the second row, you K1 CC, P1MC across.
With this cast on method, you're casting on twice the number of sitches you need, and half are the "front" half, and half are the "back". It was hard for me to wrap my head around it when i first tried double knitting last year, but I pictured it as a pillowcase... the CO edge is the "closed end" of the pillow case, and as you knit you create the double layer.
The only thing is that all the moving back and forth take FOREVERRRRRR. I hold both yarns in my left hand, and pick up only one color at a time.... I put my needle in as if I was trying to "split" a strand of yarn (but actually just splitting the 2 colors).
I think that I might frong what I have and start over.... the doubl eknit fabris is SO thick and since I doubled the yarn (which I didn't think I was supposed to do) this thing is NEVER going to felt.
