About to tackle the acoustic treatments with linacoustic/dazian expocloth on the bottom and bare drywall on top. I know how to do inside corners, but I just realized that I have no idea how to do the outside corners!!! 
Do I use 3M spray adhesive? Tack strips? Hidden staples?
I am trying to avoid the presence of any visible seams, and I am not sure if I will have a chair rail on top my acoustic treatments.
Any help would be greatly appreciated.
Many thanks!
