DIY Medusa Headband. Buy cheap plastic snakes at the dollar store (a few dozen in a pack), wire, a double banded headband, and a can of silver or gold spray paint. Wire the snakes onto the headband and then spray paint the whole thing.
Paint some pumpkins white, some branches black, add plastic ravens and voila, a very cool Halloween porch! I would put the branches in my urns on either side of the garage with the pumpkins below. It would looks so awesome!
