But... I just found out about Sherwin-Williams' Easy Change wallpaper! Yes, like most wallpaper, it's a bit pricey (on average, $70-80 for 2 rolls), but it's REMOVABLE. Really.
Better yet they have a huge variety of modern, fresh patterns. Some of my favorites from the the Dahlia collection are pictured below:
I am also a huge fan of the Beacon House Damask collection, whicn you can see here. You can check out all the Easy Change designs at the Sherwin-Williams website.
Now my only problem is picking a pattern...
