Spiders are a theme. One year, chicken wire Ghosts were all the rage. I think Spiders are really scary and that, after all, is the point.
Go HERE for a Giant Spider Web made out of trash bags. I am making this for my front door.
Sure you can pay $12.00 and get a web ready made but where is the fun in that? Why shop when you have the makings of giant spiders at home already.
Last but not least, make Spider Web Cupcakes. You can find a recipe for them and Chocolate Mice at Food and Wine's Halloween Desserts.
