Raven Under Vase
This one has a witch carved in the back so that the shadow of the witch falls on the wall behind it.
Damask Decoupage Pumpkins from Bugaboo, Mini, Mr. & Me.
This one could definitely be done with a creepy pattern, like a spider web or raven.
D-I-Y Fake pumpkins
I kidnapped a half a dozen wedding guests to carve pumpkins two days before my wedding to avoid having rotting pumpkins lining the sidewalk. It took them all day. Needless to say...I owe them for their hard work! If you would like to avoid this situation (which I highly recommend) head on over to Euclidboo and give this a try.
