Wallpapered Stair Risers

Post edit...if you are here looking for a how to on wallpapering stair risers, I finally did mine and you can read how here! It turned out be-you-ti-full :-)

For my next trick, I mean project, I'm hoping to really update our entryway. I've been messing with it forever, but now that we've bought the Ranch I'm willing to put in some real elbow grease (money, as always, is questionable).

The space is pretty small, but since it's the first thing you see when you come into our home I'm hoping to give it a little more pizzazz.   

Here's how the stairs look now.

One of the things I'd love to try is painting the risers, or maybe using wallpaper on them.
I started out looking at chevron patterns, like this:

And then I saw this:

It turns out this is actually wallpaper. Beautiful, no? I plan to paint the walls a moody grey which makes me like this picture, also done with wallpaper:

But I want walls that are a darker grey, and a pattern that is a softer yellow. What do you think of these two wallpapers that I found on the Home Depot website?

OR

I kind of love them both, but the floral costs $45 a roll and the geometric print is $86 so there's that. I think the geometric is more on trend with decorating right now, but the floral might fit in well with our this old house vibe?

Anyone done any wallpaper projects, by the way? Paint and me are best friends, but the only thing I've done with wallpaper is take it down. I actually have no idea how hard this plan might be.
