Save a tree are you serious? This idea of throwing a bed sheet over a tree and leaving it up is absolutely stupid and irrational. No one would ever think that a tree with a bed sheet over it could be a sensible center piece to a house. There is also no way you could keep the tree alive through the whole year when you cut it from its roots it’s going to die. Really just get an artificial tree it would be a lot easier and not as absurd.
