Thanks again, Ethan. I'm trying to figure out how much material to get. I'd like to get the majority of the sewing done before my seamstress leaves for a while in June.

I'm going with the trap in a bag from another thread for the corners. I'll have to think about the ceiling. Hmm. If I split a panel longways and make the cover with a flap on each side, I could put grommets in the flaps to hang them up...
