Hang paper or foam jack-o'-lantern lanterns eight to twelve inches apart from branches or porch ceilings, six to seven feet above ground. Use sturdy invisible fishing line or wire for a floating effect. This creates a magical, spooky sensation enhanced by warm LED lighting that casts playful shadows. Float in odd numbers to maintain balance and group with other elements like mums or lanterns for a cohesive porch scene that entrances passersby day and night.
