That’s my “#08 Fair Isle Hat” that just came out in Vogue Knitting Fall 2011. While I was waiting for the black and white Cascade 220 Sport to arrive from Vogue Knitting (seen above), I made up the prototype in charcoal heather and natural Dale of Norway Heilo, for my oldest son, Christian, below.
ETA: If you choose to knit it in Heilo, you’ll want 2 balls of the background color (charcoal heather, in this case) and 1 of the motif (natural). If you want to knit it in Falk, I did one that took every last little bit of 1 ball of the background (you might want 2 balls, to be safe) and 1 of the motif.
