Just today, in the book store, I flipped through a magazine featuring a space created in a very similar style. Basically mixed and matched fabrics were used to create a wall of color in a space.
I absolutely love this idea. And with an intensely white apartment, this is a very useful idea. Material could be purchased from proper fabric stores, or re-defined from any textile found in second-hand stores, even wonderful designs in new fashions. There are many clothing pieces that I love to look at, but know right well would never flatter my figure. What a wonderful way to add that pattern into your life without leaving the clothing section feeling like a total fashion flop. Of course, this would qualify you as an art geek, or some kind of geek, for sure. But geeks are good people.
