Thanks for the replies guys; I didn't have time to read it all yet, but I will later this day!
For your information: I forgot to mention that I did try laying diagonally. It was somewhat more comfortable and the excess of the sides was noticable less, but I don't think it's comfortable enough to sleep on my side a whole night long.
About the treehuggers; it's pretty long, but not long enough to wrap it around the tree twice, but I might have an idea how to accomplish that.
Well, I'm off to school!
You guys are probably sleeping right now anyway
