If someone had recommended the scenarios of colors & styles mixing (as they do above), would you have said, "Why of course. Please, that's how I roll." OR would you have shrieked in horror and tried to find your way to the nearest store that sells all variations of brown in the same style?
If your answer is, "but of course..." my work here is done. If you are looking around your home and pretty much see an ocean of different shades of brown and tan all in the same style, we should hang for a bit.
Let me assure you, I truly love brown AND beige, tan, ecru, and all the other colors that some think are boring. What I want to do is challenge you in finding ways to make those browns even more alive and vibrant in your room, without having to sacrifice the whole lot and start again. Tossing it all out and starting from scratch has never been my mantra for design. Most of us already have good stuff. Good, functional, practical stuff. It just needs a few new friends and a different perspective.
One of the reasons to love home decor mags/blogs and the like, is for the inspiration they provide.
Be inspired to work WITH what you have...AND you can always ask for help if you get "stuck"
