I have made it past the heels on the sock-blank socks. I was able to pull the yarn from the other end of the ball to do the heels. I knitted the heels double-stranded, to make them extra-strong. I have a mild fear that this will ultimately reduce the length of my socks, but logic tells me I have more than enough yarn.
I really love how the ball has two strands together. It's an excellent way to knit two socks at once.
While I was knitting on the socks, I noticed that the yarn looked remarkably like spaghetti noodles with marinara sauce. The comparison was so vivid I found myself checking my fingers for sauce stains. Can you see it?
