Sketchbook Skool is celebrating the release of the Doodle Theory pad by Nate Padavick with a contest! Doodle Theory was created by Nate, who sketched a random squiggle and told friends and family to draw what they saw. The results ranged from people to birds and fish and more, and Doodle Theory was born. Since then, Nate’s been igniting people’s imaginations with his squiggle prompts. Now he’s got a book full of them–which you can win, along with a free Sketchbook Skool kourse and a bunch of other great prizes! Click here to check out The $3,700 Doodle Theory Contest, and sketch your squiggle!
