Black Tack Pumpkins OR puff paint! I don't like the swirls (it isn't scary at all!) but maybe I could use white puff paint (even better if it were silver glittery too) to draw on a spider web and attach one of those little spider rings.
Paperback Pumpkins: 2 or three paperback: take away the cover, make a template (from the cover), glue them. color edges with orange ink pad. The central stick is hot glued before closing the books in a circle
