8. Hanging Cave Spider Webs
Take traditional spider web decorations to a blocky new level by creating structured, geometric spider webs. Use thick white yarn or clothesline to spin square-shaped webs across your porch railings, trees, or ceilings. To complete the look, craft a bright blue-green Cave Spider out of painted styrofoam spheres and square dowel legs, hanging it directly from the center of the web. The sharp angles of the web will instantly signal to any gamer that they have stumbled into a dangerous, abandoned mineshaft.
