Spiral Balloon Column [Image Source: "Ask Me For a Balloon" YouTube Channel]
We are planning a party and want our balloon tower to be 6 foot tall. I want to make a stand and I have a 3 1/2 foot pole to use will this work? Also I am planning on using 4 colors approximately how many balloons would I need for each tower?
I believe if you use a large topper (e.g. a 30 or 36 inch round balloon or a mylar balloon), you should get close to 6 feet in total height.
If you are using 11 inch balloons for your column and assuming that you plan to do a 4 cluster column, you would need about 6 balloons per foot.
Here's an explanation about achieving the spiral pattern when using 4 colors (it's for a spiral arch, but the system is the same for a tower):http://www.balloon-decoration-guide.com/balloon-arches.html
And if you need help attaching the large topper balloon, I have explained it on this page:http://www.balloon-decoration-guide.com/balloon-column-topper.html
The image I uploaded is from a video tutorial from "Ask Me For a Balloon."
They have a fantastic channel with lots of balloon decorating tutorials.
Good luck with creating your balloon towers!
