Why not have some on-of-a-kind art magnets for your frigde or on any metal surface? These multimedia magnets are made on mini canvases in various sizes, most are 7,5x7,5 cm and 6x9 cm. It is hard to photograph my work, so be advised the colors might be a bit different in real life. 

I sell these for around NOK 75 - 100
