I can fit 12 XL, and my celling is still blank. You?
Right now on my walls I have 12, plus a bunch of little things (pictures, postcards, and Absolut Ads). I just bought two more, going to put them up today. This is all just on my walls, haven't used the ceiling yet. Of course, not all of mine are super huge, I have some small posters, etc.
