I cut eight of these from black cardstock today and taped them on the window. I traced them from a bat I found online somewhere, had to make it a little bigger. Then at night, with the inside lights on, you'll see a bat sillhouette. Right now these are our only Halloween decorations, besides some pumpkins inside. I still want to tie some corn stalks (that we grew in the backyard) to the front post and that will be it for the decorations. Good enough for me.
