I used some scapbook paper and sealed it with mod podge. I measured carefully and everything seems to have lined up.

Next I glued the walls and floors in. I dicovered that the stairs did not fit like I hoped and they ended at the front wall. How is anybody supposed to use them? I will have to come up with something creative for that. I went to put the windows in and dicovered that my window sheet was printed very off center and I won't be able to use it. So i used some transparency I had around. I think I will do a stained glass for the octagone windows and just plain panes for the store area. After all the plants need the light.
