I couldn't figure it out. I looked at the site, but as I know how to knit socks already, I didn't look very closely. Just now I clicked on one of the video links and it's a video by knittingtipsbyjudy on youtube. I've seen some of her videos and find them very helpful.
Cheating is an option. . . . Cheaters never win and winners never cheat, but smart knitters who want to retain an iota of sanity do, cheerfully. ~~Kory Stamper
