8x10 black and white sign/small poster reminding students to store their paint brushes with the brush bristles UP. As an elementary art teacher I felt like I was constantly reminding students to make sure they put the bristles up in order to save our brushes from being ruined.
This is what I teach my kindergartener's their first week in art. The cap is the hat that keeps the ink in. If we take it off, it dries up. If we snap it on and wait for the "click" sound, we will have a happy marker! If we have happy markers, we have happy artists!
