I Draw Cars is a project set up by Adam Hubers and Matt Marrocco – both CCS graduates – to encourage designers young and old to pick up their pens and practice that most basic yet powerful tool in their kit: sketching.

Each underlay is printed in non-photo blue, meaning it won't be picked up by a scanner should you choose to drop it into Photoshop.
