Well I certainly feel stupid we put our ceiling tile on WAAAY wrong!!! Number one we didn't start in the corner....number 2 we used staple gun to "hold them in place" and let me tell you it was a PAIN.......ALSO the ones we bought are WAY smaller than these.....so maybe if we "redo" our ceiling (which I am SERIOUSLY considering it) I'm DEFINITELY going to buy the bigger tiles I don't care how much extra it costs I do not CARE because the smaller ones.......O...M..G takes FOREVER to put up even with a staple gun!!!!!! xD
