I had some greyish-blueish sock yarn my mum sent me. I wasn't sure if it was variegated or self-striping, so I wanted to do something straight-forward with it.
I was just going to vanilla my way through.
Instead, I went for Anne Campbell's Circle socks, a fun pattern that's just entertaining enough to make vanilla into more-ish knitting. At least for me.
These are slightly larger than my usual socks, but the structure of the holes makes the cuffs stack and stay up by themselves.
I think this pattern would be fabulous in the right kind of striping, or a loud variegated, too.
