At each end of your chosen centrepiece, add one black feather boa, 3 wine bottles, 2 wine glasses and 3 glass pumpkin lanterns with votives. Balance at each end will make your table look complete.
Stretch the white spider web over your lighting fixture in any desired way. Hang the 3 skeletons on the lighting fixture, distributing them evenly.
Stretch the black spider web from end to end of your window, starting from the top. Try to swag it from side to side repetitively, until all used, to create a gothic valance look and feel.
Using the suction cups, stick the rubber bats on the mirrors. If you don't have any mirrors, use a window or affix them to the wall using tape.
Place the 2 witch hats together wherever your guest will see them as they enter the room. Same for the large metal pumpkin lantern.
On the floor, fill 2 vases with dried flowers or branches. Ideally, they should have different heights. Also scatter as many wine glasses containing votives around the room, to your liking.
Cluttering dishes on a buffet table adds to the effect of coziness. Also, you could add items meant to spice up your theme and spark conversations!
All these items are either from the dollar store, outdoors, around the house, from your everyday life or from the recycling bin!
