The answer is no.
Here are the latest Mindless Socks.
Yarn: Regia Silk (55/25/20 merino/polyamide/silk--unfortunately discontinued), colorways Nairobi and, um, plain white? The number is something boring like 0002.
Pattern is mindless socks, of course, done with 52 stitches on size 1/2.25mm needles. That creates a very fine, thin sock that could easily be worn with everyday shoes.
I really like this combination of yarns--it satisfies both my frugality and my aesthetics. You'll be seeing similar socks as I work through the remainders of previous projects. I'm also on a yarn diet, so I can't buy any new sock materials for the foreseeable future. *sadface*
