craftgrrl | Blank wall problems...

So I am about to move into a new house with some friends, and we are not allowed to paint the walls. The current wall color is an almond/off-white like color. I am a HUGE fan of color, and I do not know what I am going to do with myself. I have been thinking that I can paint some canvas type fabric and then hang it on the wall, but I don't know because the room is fairly long and large. I was wondering how I would go about mounting/hanging it, or if anyone else has any suggestions?

I have a HUGE cork board that I fill with collage-type photos and what not but I don't want to do that anywhere else but the one wall.

I appreciate any thoughts or suggestions. You guys are the greatest!
