I loved doing this in art class. Art With Mr. E: Line Design w/Shading - Grade Very cool, fun art shading project from Art With Mr. he's an elementary art specialist. Try this with your kids (but I think grown ups would enjoy this too).
Supplication Succulent (Colorful Rainbow Spiritual Vivid Neon Plant Drawing with Copic Marker Ink on Bristol) Pretty! Id love to create something like this. Not sure if my new art class teaches with marker.
