I'm a little in the dark on this one.
A question : Portraits of what?
Are these generic like lions and tigers, dogs and cats?
Famous people? Flowers.
Obviously, I cannot answer your question.
Except to say, Every craft show is different, depends on the affluence of the area...
Nah, I keep my prices the same no matter what.
Price them for what you think they are worth unless you just want the 'pleasure' of
saying, " I sold one!"
Sorry Edward,,, I just wanted to ramble a little before I go to bed.
Good night
