How do I group outdoor Halloween decorations effectively on my porch?

Group decorations in odd numbers like three, five, or seven for balanced yet dynamic appeal. Repeat materials such as pumpkins, lanterns, or mums at least three times to create cohesion. Vary scale and height within groups to add depth and texture. For example, cluster pumpkins of various sizes alongside hanging lanterns and a spotlighted crow to tell a visual story. Intentional groupings make even small spaces feel styled and thoughtful.
