Long projects and short

Last week was one of those weeks. I did manage to get the body of Arisaig finished, blocked and seamed, as you can see. The sleeves are coming along: I started the second sleeve with the intention of knitting both at the same time once they've reached the same length.


While going through the stash, I found a single ball of Debbie Bliss Cashmerino Aran which was orphaned at the NPS store, of all places (it was $3 USD, how could I refuse?). So what do you do with 1 skein of this yarn?
OK, that was fast. Do I have enough yarn to continue?

My hands get cold when I'm working on our home office computer.
