Balloons, balloons, balloons- cheap and colourful nothing says party like balloons. They pick up the theme colour and fill space. Scatter balloons all over the entrance hall, tie balloons to each chair at the table, put balloons on the front door and bathroom door. If you have helium balloons let them go up to the ceiling and trail down their ribbons- it looks like more than bouquets do. Buy inexpensive tableware in a complimentary colour. Put a solid colour paper tablecloth down and let the kids colour on it. Scatter candy and metallic confetti and ribbon curls on the table for a great effect. All of these items can be found at the dollar store very inexpensively. Most of all have fun with your decorating!!
