There is no doubt art is messy. At home cover the table, your child and if you feel it's necessary the floor. We invested in canvas drop cloths and cut them down to size for our school tables (I did zig zig the edges on my sewing machines to prevent fraying) Too much? Use an old tablecloth to cover surfaces.
Why is art important?
Make sure you are including art in your child's preschool homeschool.
