Damn. How did we make it this long without knowing about Supermarket Sarah? This girl creates the most amazing walls using her own items and collaborating with designers such as Tatty Devine, Donna Wilson, and Fred Butler. The best part? You can buy anything shown on Sarah's walls online in her shop as well as in Selfridges. Her site is chock full of inspirational images and quirky vintage clothes, furniture, toys, and artwork. Go have a peep. It's addictive.
