so...i decided to decorate my bedroom door by sticking a few hundred pokemon cards onto it
stack of pokemon cards,
(sorry it's upside down)
and just stick them to a door.
also it would be a good idea to wipe the surface of the door with a damp cloth beforehand
and at one point i got smart and stuck the bluetack on the door first instead of anto the cards;D
i still had some leftover:/
here's the end product...with my one direction wall on one side(;
