I have another resource for you to check out. Its called Awesome Arts it has a bunch of unique resources for learning and practicing art. ( more links to follow soon!) I don't want to overwhelm my readers with all my artsy finds, but they are coming!
To start out, my plan is to create a lapbook from The ABC's of Art section ( download the one in color) and as each is introduced add work of theirs to that particular sections or topic/skill/concept.
