Sorry, one more idea. I am a very tight knitter. So tight that even using 2 sizes larger needles made it larger, but still not "stretchy". It was creepy and ugly. The author of my sock book recommended, long tail cast on PLUS double stranded cast on. It worked!!! My cuff is perfect and "stretchy". It worked so well, used the same size needles I am using for the socks. I am so proud of the first sock, I can't believe I knitted it. And yes, this is my first pair. Everyone in this forum has been so helpful and supportive. And I can't say enough about Sivers sock instructions. Her instructions and pictures literally helped me work through my fears regarding every "mysterious" aspect like heel turning, gussets.
