Spring Lettuce

How long would it take me to finish a sweater using sock yarn and size 2 needles. One year and three months. But, don't feel sorry for me. I had lots of fun time playing with this gorgeous yellow green yarn. And I would finish it much earlier if it wouldn't need two sleeves. My goodness, I was drowning in the sea of stocking stitches!
The yarn is Malabrigo sock yarn in lettuce, so soft, so fresh and so lightweight.
The pattern is Amelia from Jenny Watson "Catwalk" book, very classic but not boring.
At least, Sarah agrees it looks very green!
