Just off the top:
You could always check out your local community education program to find out if you can teach a class. You could provide a class through them, or through a community or neighborhood center. It can be an adult or a kids' class. Moms might look for something fun to do with little Billy or Suzy.
If you're art savvy you might work p/t at a local craft or art supply store.
You might approach daycare centers to see if they would offer a special class, featuring you.
Churches in my area won't offer anything that makes a profit (state law, apparently). Yours might be different.
Approach Red Hat Societies. They're always looking for something fun to do, and they'll pay you.
