I just posted to Facebook, complaining that my feet were icy cold despite wearing extra thick socks. I was very disgruntled that I was still this cold when I used worsted-weight yarn to make these socks (much thicker yarn than people usually use to make socks). But then a friend commented and pointed out where I went wrong. Instead of using worsted yarn, I should have used bested yarn and then my feet would be warm.
Groan-worthy though it is, it is such a rare occurrence that someone gets knitting puns past me that I had to share.
