Aw... a sweet little window! Designed to fit over the Facade for Even Smaller Theatre Boxes (which fits over the Even Smaller Paper Theatre Boxes). This window has a shallow flower box (1/2" deep).
If you align the bottom of the windowpanes (aka the top of the flower box) at the bottom of the niche created by the Facade, you'll have about 1/4" margin on the left, right and top edges of the window for gluing to the Facade.
See one of the photos above for the window before constructing. Fits together easily and you'll only need a bit of glue (and a sharp blade).
