Low-Budget, High-Impact room update

I saw this image on one of my favourite blogs - Little Green Notebook - the other day and thought it was a fantastic way to make a huge impact in a room without spending much money. And, you can easily do it yourself - even better! It looks to me like all that was used was some wallpaper and some trim to frame it. The trickiest thing about a project like this would be finding somewhere that will cut the trim for you on a 45 degree angle (unless you have a saw at home), and hanging wallpaper in a straight line! But if you can manage those two things, imagine the possibilities! Something like this would be great in a series of three coordinating patterns, too.
