My dad loves back to the future as do I. So last fathers day I decided to make him a fathers day card unlike any other. I used a heavy piece of cardstock & a fine point sharpie. I designed the front, inside, and back adding all our favorite quotes & references from the movie. I don't know how well this qualifies for an instructable since it's so simple but I figured I'd put it up to give others ideas that they not need be limited by store card choices. I know this made my father real happy.
