Last but certainly not least, I have been reading the just-released book "Undecorate" by Christiane Lemieux. I really enjoyed her ideas and I'm sure it can be usefull for you too.
But what does "undecorate" mean exactly? I'll let Christiane tell you:
Undecorate is about putting your philosophy first, putting your personality first, and letting your signature style blossom naturally from the decisions you make.
I wasn't sure but after reading her I'm going to buy some color to start my wallpainting !
