I'd like to mention several publications which I have found both interesting and useful over the years and hope you will too. Apart from more specialist works which will be described in later posts, there are some excellent interiors-type books within which you can see antique and vintage French items used to enhance the character of real interiors.
A series of books by American author and designer Betty Lou Phillips contain a wealth of pictures combined with intelligent and informative text. I think there are nine or more in the series. The one I bought first was The French Connection and another is Quintessentially French available from Amazon - or your local library should be able to obtain them through inter-library loan if they don't already have them in stock. On a rainy afternoon there is nothing better than curling up on the sofa and leafing through books like these. Not only do you see things used within a context but can plan new uses for your finds or make a mental list of what to look out for.
Another book which I found only recently is Antique French Textiles for Designers by June K.Laval which gives a basic history of French textiles from the Middle Ages to Art Deco and also ideas on how to use them in traditional and contemporary design.
