It's turned out to be a lot easier than I expected. I say this now because I've yet to tuck in all the ends on the backside. Imagine this knit rectangle folded in half and you can imagine what the leg is going to look like. When I'm done, I'm going to add some teeny ornaments to the tree. Believe me, it'll be cute. I saw something similar to what I'm planning on doing at a LYS.
The weird thing is that I was told to knit this rectangle, then knit the foot and later go back and stitch up the back side. The pattern doesn't mention this at all. In fact, it appears the author of the pattern assumes everyone knows to use circulars from the beginning. And you know what assuming does. Yes, I've made an ass out of myself. In my defense, I did inquire about the rectangle but nobody had an answer. everyone else was doing theirs like this too. Oh well, it's still going to look great.
I'm still not sure if I'm doing the intarsia correctly.
