for the second design element?
It's a tree! (I hope you see a tree there.)
On the leg, the path continues front and back, flanked by trees, a forest, if you will. I couldn't find a tree I liked so I made one up. I'll try to take photographs of the also ran's. One design element left. Anyone want to guess what it is?
srvana asked about how the path was knit up. The path knit stitches are twisted, separated by purls, and travel every other row. It's not difficult, just kinda... requires patience.
