It's all good.
Two socks on two circs rocks! I love knowing for sure they're the same length and I love, love, love not looking at one finished sock and thinking, "OMG, I've got to do that all over again now."
(Yes, I do have wide feet. It's true. I'm o.k. with that.)
It didn't save any time to do them both at once. It's just a mental thing.
Please be aware that I know this color was totally wrong for this pattern. From now I will listen to the crowd when it comes to hand-dyed sock yarn (I dyed this myself). Some patterns....o.k. most patterns...just don't do it justice. And vice-versa. You can't see the pattern at all in these and the colors look muddy until you get to the plain stockinette foot....where they are fabulous!
Live and learn.
