Sticking Up Acoustic Foam

Received four big rolls of second hand acoustic foam for the office!  \o/  It's kind of like Christmas! However my office is unfortunately both my recording and mixing environment, so I likely won't need all of it, but it should take a bit of the bite out of the current echo.  I have a feeling the rest of the team think the foam is soundproofing, not sound deadening - although it is probably soundproofing to some degree... for them, that is.

After finally getting some room treatment materials (aside from the ever-faithful mattress), the challenge now is mounting the foam on the wall - without either terribly damaging the foam or the wall.

Spray adhesive is typically the best for this sort of thing, but without that option I've had to get a bit creative with double-sided mounting tape:

These are works in progress.  After a bit of trial-and-error, this seems to be the method that's finally held up using the available materials on hand. It's not beautiful or tidy, but it gets the job done.  That's packing tape, glued directly to the foam (since packing tape won't stick to foam), and then double-sided mounting tape stuck to the back of that (since mounting tape won't stick to foam either.)  Turns out once you rule out spray adhesive, getting anything to stick to foam is a real challenge! 

I should have used glitter.
