Drum roll please...
The correct answer to the contest question: my clever idea for masking the change from one color yarn to another overlooked the fact that mosaic stitch and stockinette have different gauges, so there was a rippled stripe of looser knitting, where I did stranded K1 K1 K1, creating a major pucker down the center of the sole of my sock.
Four people got the correct answer, so as promised I drew names out of a hat. Here are the results.
The grand prize of a skein of Jitterbug sock yarn, colorway Ruby, goes to Susan (sb).
First runner-up of two skeins of yarn in the same colors I'm using for my socks: Alli Gator
Second runner up of two skeins of yarn in contrasting colors suitable for stranded or mosaic sock knitting: Helga (Mythen und Sagen).
And for the last-place finisher: the bad news is that you don't get sock yarn. The good news is that you get four skeins of Debbie Bliss Cotton Cashmere in contrasting colors, plus a little extra for seaming. It goes to Cindy in Oregon.
Thanks to everyone for participating. And sorry to be slow in posting the results. I thought I would have plenty of time to post before my four house guests arrived for the week... but I forgot about the part about cleaning up the house all day Saturday. (So that I could apologize for the mess when they arrived, all the while secretly thinking, You have no idea how bad it REALLY can be...)
Oh, my out-of-town friend said when she saw the yarn closet. You knit?
