Use with your non-dominant hand – If you’re right-handed, sketch an object with your left hand.

Your hands – There’s a great subject waiting for you at the end of your arm. You always have it with you, so there’s no excuse here.

A person sitting in a chair – Grab a friend to pose for you.

Different types of trees – Get outside with your sketchbook and find a nice shady spot.

A copy of your favorite master’s painting – What artists inspire you? Find one of their artworks and make a sketchy copy.

A brown paper bag – Think the crumpled piece of paper was a challenge? This one is even tougher!
