Hi again-
Sorry for the additional post, but think we forgot something. While working on the greenhouse the Mr. and I were commenting on how fun it would be to meet Bubbles- anyone who listed "hammer and rebar" in the directions sounded like a lot of fun!! Looking back, I guess we must have read some of the steps out of order cause after we finished with the door we left for the rebar to get hammered. Back at the house we sat and admired our handy work, however the Mr. just couldn't figure out how that one door was going to keep the cold out. He thought about adding more doors but had run out of wood. I decided to check your instructions again and lordy lordy, we didn't need more doors, just plastic! Now that is smart!
Here is a picture of it with the plastic! So not as big as yours, and a little different, but I think it'll do the trick. And when the Mr. acts up, he can sleep out there!
