Spider Web Window Pumpkins: Create the perfect home for a faux spiders — right inside a pumpkin. Cut a large hole in a black Funkin. Paint the inside, stem and cut edge with silver-metallic craft paint. Use old-fashion cotton spider web material and tiny upholstery nails to make the web. Push the nails and web into the pumpkin’s flesh (no need for hammering, they go right in). Tie the yarn onto the nails and wrap around the nails. Add a few spiders.
