The easiest, spooky and cheap decorations I can come to think of is dust. Don’t vacuum or clean the apartment until after the party, and just before guests arrive, you blow the dust rats out from under the sofa so they are in the middle of the floor.
Come to think of it, we should celebrate Halloween more often.
I feel like it is still so early to be decorating for Halloween! When does everyone else think it's acceptable to begin putting up decorations?
One of the easiest ways of decorating I think is to get a marker pen and a bunch of clementines to create miniature pumpkins by drawing faces on them! Very effective and less mess and effort than actual pumpkin carving.
