Definitely plan to buy the squeegee tool for smooth application, and also get an exacto knife for trimming the excess. Also you'll need a tall and sturdy step ladder so one of you can "easily" reach the ceiling while the other stands back at the other end of the room to be the alignment guide! We did this when I was verryyy pregnant so hubby was up on the ladder and I was the one calling out: "Move it 2 milimeters to the left, ok 5 milimeters upwards, ok stop! Right there!" :D
