https://www.3m.com/3M/en_US/p/d/b5005604185/ I used these when I use to rent. You might need a different size depending on the weight of the panels, but they removed cleanly when I'd redecorate.QUESTION!
How would you hang these acoustic panels without completely destroying the wall? They are made of felt and pretty thick (as shown in 2nd photo). The manufacturer suggested construction adhesive. Yeah, right. These puppies are coming with us when we move, and I HATE patching drywall.
Thanks in advance for any help!
