To make bats for Halloween wall decor that look stylish, start with black cardstock or heavy paper. Cut bat shapes in varying sizes, focusing on simple, clean outlines with tapered wings for a sleek effect. To create a swarm or movement effect, arrange them diagonally or circling a light source like a pendant lamp. Use removable mounting putty or low-tack tape to gently stick bats to walls or around doorways, ensuring renter-friendly removal after Halloween. Cluster bats closer together near focal points and space them out as they spread to add dimension. Keeping the color palette tight with only black bats on neutral walls ties into a cohesive, minimalist theme that looks polished and modern rather than kitschy. This simple paper bat method is affordable, reusable, and high-impact for stylish Halloween decorating.
