I created the window with the Centerpieces Spooky Window Die-namics. Behind the window I added a piece of Banana Split Card Stock and then softened the feel with a piece of Vellum. I used the Witch Way Is the Candy? Stamp Set and Die-namics to add the sentiment, bat, and the pumpkins.
I added a ledge to the window by cutting a rectangle to fit the window. The sentiment is cut out with a die in the Sentiment Strips Die-namics.
