Art Class @ Monroe County Public Library Marathon
Oct 3 @ 9:30 am – 11:30 am

Self-expression through art is an important part of human nature. You don’t have to be in art school, or create marble sculptures, or create realistic paintings to be an artist. Whatever you create is an extension of you, and it is beautiful in that regard.

Join us on Tuesdays from 9:30 to 11:30 AM to let your creativity shine!  In this class we will explore different mediums such as sketch, paint, multimedia and more!
