The Metropolis pattern by Wildhorse Farm Design and bought here at the Loopy Ewe was a very challenging pattern for me. I had done the first sock awhile ago and wasn't sure I'd do the second sock. So, my challenge was to do the second sock. Surprised myself and completed it while recovering from surgery when I had some time to sit for hours and focus on the pattern. The yarn is a custom job from Doodlebirds Creations.
