Design your own Filofax cover

The Filofax Doodle:

Be creative and individualise your cover using the spiral doodle tool provided. No diary is included, so it is ideal as a notebook or add your own choice of diary. Includes a small square of material to test your pen.

Can’t help thinking this should have been a wiple clean surface with a magic pen, rather than a one shot design process. Ah well, still cool.
