Maps as Wallpaper
I've got a map urge today -- it's never very far away frankly, and it's one of those design elements my husband Ben will also go for (as opposed to skulls, for instance). I found these two rooms via Design Crisis.
Lovely.
I've had these images from a very old issue of Martha Stewart in my inspiration file for a long time.
For an especially affordable set of large maps, check out the USGS maps of your locale. For $8, you can order maps of any location that are around 6 square feet.
