I almost made it. I ended up knitting the ribbing on the cuff of the second sock, binding off, and sewing in ends in my mom's living room yesterday. I made a mistake and did an extra pattern repeat in the gusset of the second sock, making it about o.5" longer than the other. Luckily, Mom said one of her feet is longer than the other because of arthritis in her toes. Guess that worked out well.
