Free, but if you like it and want to thank me with a cup of coffee, I could always use the caffeine.

Several years ago, I devised the Evil Sock Genius Lessons, instructions for making socks with any yarn, any gauge. Over time, I have tweaked and refined these guidelines, and now present a basic men’s sock pattern that is, like the best work of an Evil Genius, sheer elegance in its simplicity.

If you or your victims are not fortunate enough to have medium-sized men’s feet, rejoice: Mastermind Sizing Variations are also available.
