I'm in different when it comes to this topic. There can be a difference between the two, arts being more heartfelt and meaningful or crafts just being fun and something you do when you have the time. But like you said, Mrs. Martin, some of your family members do it and sell them at craft shows. They probably make their "art" heartfelt and love doing it.
I think the word "craft" or craft making is just another word for "art". It just depends where you were from. Some states or cities may you use the word craft in-place or the word art.
But I will agree that crafts seem to be a little more "corny" then artwork.
