19. Creepy Crawly Spider Invasion with Giant Web
If you want to create a high-impact look that will make your guests’ skin crawl, a spider invasion is the perfect theme. Start by creating a massive, intricate spiderweb over the entire fireplace breast using thick, black yarn or white clothesline rope, anchoring it to the wall above the mantle. On the mantle itself, place a few large, furry tarantula props. Scatter hundreds of varying-sized plastic spiders across the shelf, crawling out of the fireplace hearth, up the sides of the mantelpiece, and spilling over the edges. Keep the rest of the decor simple—just a few white pillar candles—to let the dramatic, creepy-crawly invasion take center stage.
