Hi Jean - I bring home my sponges and watercolor trays and cups and run them
in the dishwasher. I buy sponges at dollar store (package of 4), cut them
each in half. I find that many of my students (especially the youngest - K,
1st and 2nd) come to class with hands so dirty their papers are smudged before
they even begin, so I let them wash up whenever they want! My first year
with a sink in my classroom - I love it!! SandyJ
