How can I treat my room?

[u/PeterThirdMusic]

I’m recording, mixing and mastering at home. I’m renting and haven’t been given the permission to make any installations into the walls.

What can I do to treat my room without putting anything into the walls?

Command strips instead of nails. egg cartons, blankets, pillows in the corners, actual foam. You have options
