Honor the History - Wherever you live, honor the history of your place. Bring together the character of your place and comfortable elegance. Your design should feel like it was made for your home's age/style.
Tradition Over Trends - There is an old French saying that says, "the more things change, the more they stay the same". Don't decorate according to trends. Stay with the tried and true. Pick your large pieces that will last a lifetime in style, and use easy to get rid of trendy things if you must have something on trend.
Eclectic Elegance - Mix things up! If it's too perfectly designed, it won't be natural. You want your home to feel like it was easily put together, but elegant. Using different pieces will make it unique.
K I S S - Keep it Simple, Silly! - Don't try too hard! Mix old and new things. Use special keepsakes from your life to make it feel personal and lived in.
Use it All - Use and reuse everything! You don't need a bunch of new and fancy things for French decor. Second hand stores and family heirlooms that can add history and serve a purpose is very French.
Color Cues - Don't just use a neutral palette. Using color to meld old and new pieces is a way to make your space flow.
Life is a Breeze - Practical Luxury. Use this mentality when you design your home. If you carefully design the space around how you live so that it is easy to move through the space with little effort, then Life will be a Breeze! Vive la France!
