Since you'll be framing, the adhesive only needs to hold for the cutting process.  A light duty spray adhesive should work just fine.

Thanks Brian, wouldn't even be thinking about this without your advice here on AC (and Ethan, to be fair).

Any ideas for framing? What would you use?

Stack of triangles.

Thanks, I would love to do that but it's only possible in one corner of the room, and this room is temporary anyway, that's why I figure tricorners are something easy to move to a new room, a single hook on the ceiling.

Framing for what you're considering will just be a 3 dimensional geometry exercise coupled with a lot of patience and a good compound miter saw   

The other option is to use drywall corner bead riveted together and cloth held around and attached on the rear via velcro.

I like that idea, thanks, will look for some bead.

Fwiw, I spotted an installation detail in our office conference room a/v system that may be useful here.    

They used residential aluminum frame window screen materials.  You can find window screen replacement/repair kits at Home Depot/Lowe's.  You can buy just the frame/track pieces which is all this method uses.  They cut the alum. track into the fascia rectangular shape, then wrapped the acoustical fabric over the outside face of it and folded over the back side.  The fabric gets held in place by the plastic rope pressed in to the groove on the back side, like you would normally do with the window screen fabric.  Velcro strips are then  installed on the back side of the frame and where ever you want it installed.  Easy on, easy off.
