Peel and Stick Configurable Balloons

Saw a square balloon at the store and thought "What if you put magnets in these things that allowed you to put them together in various configurations like blocks with numbers showing which number goes where for various floating sculptures?" Then I thought "Why magnets, why not just peel and stick on all sides?"

To my surprise, I see that the magnet portion of the idea was put up by somebody else only this month.

My idea's different enough that I'll post it.

Square balloons with peel and stick corners that have numbers on all the sticky areas that you use to build various floating sculptures, sort of a paint by numbers for sculpting.

You'd pick a sculpture, buy the necessary amount of balloons to make it and follow the directions. "On the starter balloon's #6 attach the next balloon's #3. On that balloon's #8 attach another balloon's #2 etc. until the thing is complete.
