I picked up this yarn at Twisted. The yarn is Yarntini DK weight and the colorway is Twistini, which is dyed specifically for Twisted.
This was also a really good opportunity to try two socks on one circular. I'm only using a 3.25mm 32" Addi and it's a bit tight. Another time I think I might opt for a 40", but the needle size is about right.

How I Split the Yarn Into Two Balls---
I wanted to split the yarn in half so I could knit two at a time, but I didn't have a scale or anything, so I had to improvise. I would all the yarn with my ball winder and swift, then I began winding a ball from the center pull. Once I thought I was nearing the half way point, I started another ball from the outside end, and wound that until it was about the same size as the first ball. Then I went back and forth until I had two same sized balls.
This method worked really well for me, and I will definitely do it this way again.
