Making Number 16 on Balloon Columns by: Arizonas Balloon Artist
You can buy a base and pole from Conwin Online. Take two different colors of 6 inch balloons, inflate two balloons of the same color and tie together loosely. Take the other color and do the same. Wrap the two sets together to make a quad and repeat this process for every row of balloons you need.
Buy Aluminum rod and bend into 6 shape. The number one can be made from one column. Take 5 inch balloons and undersize them to 4" and cover with quads. Secure to top of column with cut rubber bands tying from the bottom of the 6 to the first two layers of balloons on the column.
