Knitter K. recently took my class on Knitting Two Socks on Two Circulars, just before she left on a cycling vacation.
She wound up two balls of yarn, threw them in her backpack, and got on her bike. She cast on as she started on her trek in the Czech Republic, and as she cycled into Hungary, the heels were done and now she's into the foot.
Love it! I look forward to the follow-up photo, of her wearing the socks on her bike.
