I don't too many windows for fall but the Southwest Diner in Boulder City always has me do their's up for Fall.
They do a really cute job of decorating the outside of their building.
I tend to paint really large items so its easily seen as a person drives by. Too many small items can just look cluttered.
They like to keep them up until it's time or snowmen so its just pumpkins...no jacks.
They have outdoor dining so this is one busy door. It takes a while with all the interruptions.
P.S. They have really good home-style food. I highly recommend them.
