Why not paint and hang gorgeous William Morris fabric drapes instead...

Well, because she didn't ask for drapes.

I'd use a more generic term to search, such as arts and crafts wallpaper. That will lead you to many companies, like JR Burrows or Burt, etc. not cheap, but much less than the real thing.

Oh you are so sassy TATTS!:)

Will check into them. The only windows in the dining room are french doors opening onto the back porch. I really don't need drapes. Thank you for your input!
