How about I tell my art teacher no.
What are you going to say no to them about?
I'm going to tell them that I'm not going to do the project.
Telling your art teacher that you aren't going to do the project is disrespectful. You're supposed to listen to your teachers and when they make reasonable requests of you, you should follow them. I think you should agree to do the project.
Fuck you, I am going to do whatever I want.
Teachers ask you to do things for good reason. If you tell them no you will probably miss out on learning something.
