I'm in the middle of filling up a very long wall with a mismatch of different things and colours, and this is one of them. It started life in about 1996 as a framed poster of Bart Simpson.
A very simple makeover, all I did was:
take the backing board from the frame
wrap it in pretty paper like a present
tie bits of string around and tape in place
put back in the frame
hang things up!
Of course if I'd painted it a different colour then it would've taken longer (am I the only one who constantly ends up with tiny finger prints on anything I paint because I'm too impatient?!).
Luckily I already liked the colour so it was up on the wall within half an hour :)
