Using this Melissa & Doug water - painting set is super easy. First, get a cup of water and dip the included paintbrush into it. Then, moisten the paint palette on the page. After that, start filling in the pictures of the cool vehicles. When you're done, you can tear out the perforated pages cleanly to display your masterpieces. As for maintenance, keep the paintbrush dry when not in use. And store the set in a cool, dry place to make sure the pages stay in good condition. Also, remind kids not to use too much water as it might make the pages soggy. Have fun painting!
