a very good article in Glamour Living listing 10 ingredients for a happy home. I fully agree with the importance of light, plants, scents and fresh air . These ingredients clearly help creating the right ambiance ; you and your friends will feel the benefits. This is also part of my conception of decoration and what I always advise my customers. I would add the many benefits of candles that can diffuse some very sophisticated fragrances ( Dyptique candles are amazing ! ). Also consider a HEPA air filtration system that can really help freshen up the air . At your disposal for any advice. Happy New Year and all the best for 2016 !
