Four types of balloon walls are included in this template download, in 4 different file types. There is an accompanying video on Youtube on my channel that takes you step by step on how to color it in and scale it, and then determine how large to inflate the balloons for desired results.
This download does not include instructions on how to make the walls, only blank templates so you can color it in and make your own wall designs.
Bonus file is the Excel sheet to convert the dimensions in your graphic to actual measurements to inflate the balloons.
