In the end, I decided to just a plain vanilla sock*.
Do you know that as long as I have been knitting socks, this is the first time I've ever made a plain vanilla sock? It is.
I kinda like it. It knits up really quickly, not having to worry about a pattern and all.
I think I need to do some more of these.
*For those of you not in the knitting know, a plain vanilla sock means one knit all in stockinette stitch, without a pattern.
