No, that's not -up- but UP, pronounced "Youpie" as in the Upper Peninsula of Michigan. I started these socks on our way back from the UP this summer. The colors of the yarn remind me of the sky and lakes and trees on that trip.
This weekend we spent driving to and from the farm so I got a little time to knit in the car. I got through the heel on the first sock. I have two balls, I may be able to get several pairs of socks out of the two balls, as the first sock is barely making a dent in the first ball.
