Knitting: Fair Isle Socks

I had never knit Fair Isle before, so I thought a pair of socks would be the perfect introduction to learn this technique. I watched this video and started casting on using this pattern from Patons via Ravelry. I used some Berroco Ultra Alpaca and Knitpicks merino wool from my stash. The knitting was fun and went by quickly. It wasn't as hard as I thought it would be and I think a Fair Isle sweater would be doable. I ran out of the dark green yarn for the foot of the second sock, so just continued with the lighter green. They're very warm and cozy!
