When I had to make a art gallery for school I decided to change what the instructions said for me to do and make it into a art gallery for my American girl while still meting the requirements. I made a sun roof and extra art. Of course I had to make it a little bigger to fit my American girl. But I still wanted to make it look more like a real building. So I made real doors and painted the doors. I also painted the sides to look like real brick. After I finished and it was done drying I set my American girl in it. It was perfect.
