Lastly, don't forget the decorations. Decorations will add value to any party you throw. You don't have to go over the top, unless of course you want to. Decorating a room can be as simple as adding balloons and streamers to help give the room a more festive feel. if you feel like going all out banners and centre pieces are great, but remember decorations should not be so overblown that they hinder the party.
