You don't need to an art-school degree to create your own impressive piece of abstract modern art. Give a plain white wall a supercharged injection of colour by sticking a row of wax crayons along the top edge of a canvas and blasting with a hairdryer. As the wax melts, cascading rivulets of colour will drip down the canvas to create this dramatic effect.
Vintage clocks are works of art in their own right. These mid-century starburst-style clocks look great hung together as a group on a plain background to create a statement wall.
