That is just so ridiculous, isn't it??!! Who are they to say who's hard earned $$$ they will and won't take!!!
Sharee, a gf of mine has some really beautiful wallpaper that I think you may like. I'll ask her where she got hers from (hers is red, but in the same vein as what you described!)
We were thinking of putting wallpaper in DH's study. He loves green, so it would have to be green - probably lime!! We've actually seen one we both like, just not sure exactly where to source it...and now I'm a little nervous about being accosted by intimidating wallpaper salespeople!!
I don't have an interior decorator....it was all done a la petal!!!!!!!
