First I measured the inside of each room: height and length around the three walls. Then I cut.
The last thing we did was to draw beautiful doll house windows with our Prang colored pencils and art paper. We cut the windows out and "installed" one in each room of the doll house using Mod-Podge.
The window in the second picture is top is mine. I'll have to give you a close-up later. It's a delicate tree outside with a cardinal in it. My daughter's window, the one in the third picture, is lovely. I love it! There a "huge oak" outside, and a sunset.
