attaching fabric to cover absorbent

I am interested to know how in pro studios the fabric is mounted very neatly, i.e. very little trim is used to hide nails. How do they do it? Is the fabric glued or is there some other thing involved? Here you can see some pictures that show pretty well what I mean: http://www.johnkilgore.com/stacrpics.html Greetings, Dirk

Those ARE very nice wall panels! But I think the operative word is "panel." Those appear to be frames that have the fabric stretched across them (kind of like an artist's canvas) and stapled on the back or side to cover the staples. A word of advice though: it takes a lot of stretching to get the fabric to look nice and tight and that will take a lot of bracing to keep the wooden frame from bending. len
