Perfect! Love this idea for New Year's Day. Why not start the year off right with a bright and beautiful rainbow. Thanks so much. Hope you have a bright and beautiful 2022.
Hi! Thank you for this it was so helpful. I have a client asking for an 8ft rainbow (in height at the highest point) I know that I would just add more to the ends so that it will be longer at the highest point when I stand it up and install. but what if I wanted to make it bigger would I just inflate each size a little bigger? For instance you said 3.5, 4, 5, 6, 7, & 8 for sizes. Could I instead do 4, 5, 6, 7, 8, & 9 or even bigger?
