Should I Go For It??

Thank you all for your encouraging comments about my last post. I am happy to say that my writer's block is dwindling and I am slowly getting my blogging mojo back in gear!

What if I installed a curtain rod and drapes? I could pull the panels back during the day and have the privacy I need at night. Here's the dilemma and where I need your opinion...
I am trying to go for the less is more mantra and don't want to crowd my spaces too much with things. I am worried that if I try this, it might look too busy in my little foyer nook, as the space isn't that large to begin with. I love the way these two images look, but their foyers are also larger than mine. I also worry about drilling holes into the wallpaper, as that would be so permanent.

Any thoughts? What would you do??
