Test Before You Paint
Please, for your own sake, make sure that you test paint on your walls before you dive in headfirst. We understand that you're eager to get the job done, but if you make a serious mistake, there is no coming back from that. Well, unless you're into completely repainting your whole space...
Think Before You Paint
Purchase swatches, get some free tester paint and ask a friend to provide a second set of eyes for you. It's easy to make mistakes like this, especially if you're trying to rush through making your house beautiful and livable. Be patient and disciplined with yourself and your space will thank you.
