Use pink and blue color paper to make bows and paste these handmade bows on the walls of your party hall. You can cut cardboard into the shape of bow and decorate it with colors and keep them as centerpiece on the tables of the guests. Inflate many white color balloons and tie bow to each balloon using colourful ribbons and spread these balloons on the floor. Use pink and blue dupattas as drapes for decorating the walls and ceilings.
