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. E. he's an elementary art specialist. Try this with your kids (but I think grown ups would enjoy this too).
Sadie Priss: Anthropologie-inspired Art This is her finished product. But consider this the possibilities are endless! Color the flowers to your choice and/or paint the canvas to your choice. White on White is very popular these days.
