How much do you charge per cookie for your cookies? For like a 3 inch cookie.

are you talking drop cookies or rolled cut out decorated cookies?

Sorry. Rolled our sugar cookies, decorated with royal icing.

general rule of thumb is $1/inch, based on the widest part of the cookie.

Exactly what Indy said. And then if the cookies get super complicated, (as in you're using tons of different colors) I have heard that people will charge a bit more.
