One of our family traditions comes from my childhood. My mom has always been creative, and I love that about her. Our house had something no one else's did when it came time for Halloween - Ghosts in the windows.
Some of them were genuinely spooky looking and some were more friendly - basically, the older we got, the scarier they got. She would draw, and then cut out a ghostly shape on white butcher paper (get this from your local school or copy store) and then cut out circles or ovals for their eyes. There were various sizes and they would appear to be peeking out from the sides of the windows or from the window sill. My mom put some in nearly every window; it was great, spooky fun.
Pictures to follow - we have some ghost surgery to perform. If you laminate them, you can store them rolled up in a poster mailing tube ready for next year's haunting.
