Hi!
If you want to build a new house or re-work your old house, i'll tell you Pinterest have sooo much idea for it. From the rustic to modern, go all white or go crazy with mismatching color chair, there are plenty! I love pinning my favorite interior decor in my board in Pinterest. As you can see mostly, i love mismatching color for chair, i think it's kinda cool. Having all white paint wall but you have these colorful furniture, that's a dream! Below is some of my favorite from around Pinterest world, please go ahead.
