The whole corner I've taken over:
I use the boxes from my Japanese snacks to hold my pens and scissors and whatnot. Spare dollhouse furniture and shelves hold deco items. My water colours are in a fuzzy pencil case, and my crayons are in a Marc Jacobs makeup case. A Hello Kitty sugar canister houses my Polymer clay and an old Easter basket keeps my paints organized.
I work at a movie rental place so I get to take home old movie posters. I hang vintage wrapping paper, a Little Mermaid fannypack and Tootsie Roll string lights from the tacks that hold the posters up.
My desk is kept pretty empty for doing crafts. I plan on deco-ing the lamp following a tutorial found here
