Can we talk about wallpaper for a second?

I am absolutely sure that my mom is going to get a good laugh out of this post. While growing up, it seems like wallpaper found its way into almost every room in our home. Don't get me wrong, it was completely fabulous wallpaper and totally on trend for the time being....but we still gave her a hard time about it. Then something happened. I realized that I was partially wrong and that some wallpaper can be utterly amazing. So, I must say, Mom....you're wallpaper days weren't that bad. Sorry for giving you heck about it! :)
Onward. Wallpaper has been on my mind a lot lately. In a 'I just really need to get my hands on some awesome wallpaper now' kind of way. It can literally transform a room. Basically, it is kind of intoxicating (but in a non-alcoholic fashion of course).
I've been daydreaming of exactly how to use this in our home and am trying to really think it through because it is a pretty large commitment. First, nice wallpaper isn't cheap, and second, wallpaper is not as simple to undo as paint. Read: commitment. I have determined that for now, the guest room seems like the best candidate. It's a room that will hopefully stay a guest room for a while (we can just cram future children into the same room-right? It'll be good for them). I gets a lot of natural light which makes me think that it can handle a big statement. Also, the wall that I am thinking of to hang the wallpaper on has a large window on it which means I will probably only have to purchase one roll. So far, so good.
Since this is still in daydream mode, here are a few rooms that have inspired this new found love of mine:

and here are a few of the wallpaper swatches that have caught my eye:

The rooms just come alive with energy and interest, don't they? I think that since the room I am hoping to add wallpaper to is a bedroom, I am really drawn to organic patterns- especially when color is used well within it. I tend to prefer floral pattern the most, but it will have to be just the right one in order to get my husband on board. He's not the biggest fan of floral but that's okay. We all have our preferences!

So, what is your verdict? Are you as enamored with wallpaper as I seem to be?
Mom- thoughts? ;)
