My niece loves hanging out in my turquoise living room and so do I! It's a really welcoming shade of blue and the more I live with it, the more I love it. Please disregard the unpainted baseboards. I ran out of steam. And, of course, she gravitated towards the worst section. The rest isn't as horrible.
I primed the walls and put down plastic everywhere. It kept slipping on the couch, but I managed to keep it paint-free. I wasn't as lucky in my car - I have no idea how I ended up with blue paint on my car door.
My brother-in-law came over and helped with the roller parts, which was huge. He did two coats in the time it took me to cut-in two walls.
When it was all painted, I was first like - wow, that's a LOT of blue! Especially with everything still covered in plastic, it was a lot to take in.
