I did do a side yard with a great pumpkin background (snoopy rising from pumpkin patch silhouette) from a background scene setter I got from orientaltrading.com. I attached it to styrofoam sheeting, also had Linus and Sally "standee" characters from there, placed by it. And lots of real pumpkins placed in front of the great pumpkin patch background scene. It was soooo cute. Then, other little tomato cage ghosts scattered in the yard. Sheet over styrofoam head, I drew cartoon ghost face directly on the sheet with Sharpie permanent marker. Gave them cute, silly, faces since kid friendly theme. Carved pumpkins with peanuts characters. The rest, farm/scarecrow/pumpkin motif. Raffia and pumpkin lights along fence. Scarecrows, hay bales scattered throughout.
Big almost theatre sized home made screen made from firring strips, decorated frame for fall, with leaves, cornstalks at the side, a few crows. Projected singing/story telling jack-o-lanterns. 3 large hay bales for seating. Friendly skeletons in the window.
