Wallpaper Pretty Please?

After stalking an array of interior design blogs and magazines, I have noticed a certain trend- wallpaper is making a come back. This isn't your grandmother's wallpaper though. This new breed is super trendy, edgy and vibrant, and makes you wish you had the courage to try and make one wall in your house look as good as these do:

A dressing / sewing room fit for a princess

Hybrid wallpaper at it's finest

Bit of an optical illusion

Damask por favor? I LOVE this room
