Which Wallpaper?

One of my dear friends asked for advice on wallpaper for her living room.  She was wondering if she should go with one of the Orla Kiely prints from Harlequin. Now, I LOVE Orla's work, i'm a huge fan. Her signature print has been a constant cheery friend to me over the past decade.   However I believe the market has become soooo over saturated with it at this point, so i'll propose a few more alternative wallpapers that I love (and would want to live with). However I do understand wanting to live with a cheery old friend. Oh the choices!
