I am a big fan of Chateaux-related TV, and in recent years, there have been programs on British TV celebrating these wonderful French Chateaux and the lives of the people renovating them back to splendour.
Their inspiration comes from many sources, but I have on sale a book which shows many floral designs that can be freely used for wall decor such as wallpaper or murals, or even can be used for wrapping paper and grettings cards.
The flower designs are SO elegant, using design elements of the 18th and 19th centuries - take a little peek, and if you would like further information, it is listed here:
