Maybe it's because he's french and had a fixation with the idea of the American old west, but when I was young my dad used to drag me around to the Rose Bowl to buy awesomely bad thrift store paintings of cowboys, cactus and horses, sometimes even40's era Indian Chiefs. As a little girl I did not have the same appreciation that I have today (I've even borrowed certain of the paintings here and there). Part of me wants to borrow them all to cover a full wall in the bathroom:
The bathroom can be a great place to go big with color or with overscale artwork or fun collections that might not make the same impact in another part of the house. I like this collection of deer prints from gentillefille's flickr set that she picked up at a thrift store and put on display in the bathroom (most everything else in her bathroom is thrifted too!). Do you keep collections in the bathroom?
