Reading Tree

I have this "Reading Tree" in my room that my uncle and I made.  I have been planning (all year) to put some fake moss type stuff on the bottom (it's totally been in my trunk for 5 months) But the bottom of the tree gets so dusty.  --We haven't had cleaning staff for three days in a row just this week. Any ideas on how to make the bottom look better?  I have another mini couch to put under in too but I wanted to make it more "tree like." I also want to be able to change the leaves for the fall  but I don't know if that's feasible!! I tried to put some lights on the tree around christmas but note to self: I need a longer strand next year!

I hope every year I can add something else that's a little strange and cool to my classroom! I would have loved this tree when I was little as well as my reading corner with my miniature leather couch and miniature reclining chair.    Anyone have any neat stuff in their rooms?  My friend when I was young had a giant (at least 6 and a half feet tall) Ticonderoga pencil and ruler.  I wish they still had it I would totally buy it off of her family! Post your cool classroom pictures/ideas here!
