I am a teacher, but a local cake shop is hiring full time. They make quality modern decorated cakes. I was wondering how much a decorator would make working for someone else......just curious!!

It would largely depend on location and your experience. It could be anywhere from $10 - $20 per hour.

Here is the relevant salary survey:
