Best way to hang Ceiling/wall panels?

Looking for the best way to hang ceiling/wall panels. I'd prefer to not have to add a bunch of hooks/anchors into the ceiling, so any more elegant way of doing this would be much appreciated. I've searched, but have not found anything concrete at all on how to hang these things aside from maybe a post a couple years ago by Glen about using Ook hooks/anchors. Anything with pictures (or anybody able to share pictures of how they did it) is especially appreciated.



I purchased some GIK panels a couple years ago, and built some of my own that are structurally identical (2" wood frame in back, muslin covered, etc)... So 4" GIK traps are what I'm looking to hang Ceiling/Wall (I believe they call them the 244 bass trap).



Thanks for all insight... And here's to hoping that covering my entire left ceiling/wall corner with panels will help tame a nasty 50hz mode.
