I'd like to point out that I would never advocate spraying on walls (not least because I'm no Banksy) however if you have access to some little cans then why not go mad on a birthday card! Okay so I am not that good, if it had been me spraying with mini cans the paper would have remained clear and the desk and walls would be splattered, so I chose the next best option, my printer, Dr Digi's Spray Can image and some ProMarkers! But the thought was there! You can find the Spray Can image HERE, and here's the best bit- it's free!!!!!
