There is no other website that I'm aware of that has the answer to this problem. :shrug: I looked and finally figured it out on my own!
After the the last knit stitch you purl into the back of the first purl stitch and instead of wrapping the yarn the usual way (counter clockwise) you wrap the yarn clockwise. On ALL subsequent rows you purl the stitch as you normally would, even though it's twisted, and wrap the yarn clockwise. Wrapping clockwise uses less yarn and the twisted stitch also helps tighten it up.
I am so happy and proud of myself for figuring this out! I will get more photos and post it on my blog in the next few days.
