Thanks to Shai Perednik, an IT guru and developer, users can now find and download free PDF templates for sketching, wireframing and note-taking.
According to ShaiPerednik.com:
Sketching and wireframing are a specialized style of drawing, used for fleshing out preliminary complex ideas, group brain-storming, a lo-fi method for evaluating interaction concepts, and as a way of roughly perfecting a design technique.
Sketch and wireframe paper is essentially drawing paper that is designed specifically for this purpose. You could use it for web page design, web app design, architectural or structural design, graphic design, movie direction, animation… basically any type of design that needs a physical creative outlet or group collaboration.
Not all sketch and wireframe sheets are universal, most are specialized for a particular medium, such as storyboards and specialized grid paper (axonometric perspective templates).
