Spiral Streamers – DIY Party Decor: Take a sheet of heavyweight construction paper or card stock (8.5 by 11 inches is fine) and use scissors to round off the corners. Then start cutting the spiral. Begin from the outside edge and start cutting a strip about one inch wide. Work your way around making a long continuous spiral until you reach the center.
DIY Ceiling Swirls. You could buy party store decorations, but these will take just a few minutes and cost a lot less – get a few pieces of posterboard, cut spirals, and then hang them from the ceiling for a fun and festive look.
