I love how this hat looks! Make a basic helmet and embellish it with spirals of different colors. Fully inflate three balloons of whatever colors you choose–school colors, sports team colors, whatever. Insert one of the fully inflated balloons through the top of the helmet and wrap around, spiraling balloon and lock twisting at the end. This is another balloon hat that needs a lot of clearance.
Note: If the wearer has a large head (teen/adult), you’ll need to stretch the balloon you use for the helmet to make it fit.
