I posted this on another blog a few years ago, but they are still relevant! We use these printable sketch templates for brainstorming. Combine these freebies with a stencil kit from UI Stencils (http://www.uistencils.com/products/iphone-stencil-kit) and you’ve got all the tools for the next Angry Birds in your hands :) Enjoy!
