Balloon costumes are something else entirely.
You're not just constructing decor. You're taking something that shouldn't move, and making it move. The moment people meet it, you'll see the same thing happen on their face every time: stunned, then grinning.
That reaction is the magic. It's also the business.
We sell our own costumes regularly, and they turn a genuinely good profit. This isn't a fun extra for your portfolio. It's a booking waiting to happen, and one day is enough to learn how to build it, perform in it, and sell it.
