My friend did it in her dining room and it is perfect!! I just bought the stuff. She used the RL roller for the first coat-applied lightly. She cut in with a little roller as she went for ease. Then she used the "Wallie" to do her X's. Her room looks phenomenal and she only used one gallon for a 12x15 room with only 3 walls above the chair rail. I'll let you'll know how mine goes this week.
