Do creative writing supplements help you or hurt you?

I don’t necessarily want to study creative writing in college, but it’s one of my more important extracurricular activities. Do you think it’s worth submitting a 2 to 3 page supplement of some of my best work? Or will having really great essays/creative writing listed in my extracurriculars be enough? My fear is that my creative writing isn’t strong enough to truly help me and will just make my application unnecessarily longer. Do supplements have that much value?
