Blowin' in the wind

In September 2012 I set about spinning a jumper's worth of roving from the peedie mill on North Ronaldsay. 1200 grams of it - 400 grams each of three colours. 

I am ashamed to say that I have only today finished the task, when I washed my skeins and hung them on the line to dry. 

Better late than never, eh?

I wonder if I can knit the sweater in under three years.
