hey guys, i am just looking for a better way to put up orca along the walls and ceilings. i've seen some of you guys do it and make the seems line up really even over lapping each other. this is for a sealed room. i've tried to put it up before but it was really hard to start in a corner and work my way to the other side of the room. what tips do you guys have for cutting/measuring it out so well?
