Winding Schoppel das Paar Yarn

I'm getting ready to cast on another pair of Rebound Socks, but before I do, I need to wind my yarn into a cake or rather into two cakes. These socks are knit with Schoppel das Paar yarn. It looks like a single hank of yarn, but it's actually two matching hanks twisted together. That allows you to knit two socks with identical color patterns.
