Using this color by number paint marker kit is a breeze. First, take out the artboard design you want to work on. Then, look at the color guide to find out which color corresponds to each number on the artboard. Pick up the right paint marker and start coloring in the numbered areas one by one. The water - based markers are easy to use and will flow smoothly onto the 2mm - thick artboard. Once you've finished coloring, place your art on one of the removable display stands to show it off. Remember, the markers are water - based, so keep them away from water before you're done with your artwork. Also, since the kit is non - toxic, it's safe for kids, but adult supervision is always a good idea. To keep your markers in good condition, make sure to cap them tightly after use. This will prevent the markers from drying out, and you can enjoy many more creative sessions with this awesome kit.
