ChristianG's corner traps

I dug up a few pics of my corner traps. The first 4 are are the pics before the finishing panels were fitted.

I just ran some 2 inch wide strips of MDF from floor to ceiling, equidistant from the corner. I had some fluffy pink insulation lying around, so I stuffed the corner, then fitted the Knauff (rockwool) panels on an angle and stretched a breathable garden underlayment fabric (black stuff) across the front to keep the rockwoll in place, and keep fibers in.

From there I made rectangular frames and stretched some colored material over the frames and attached the frames to the MDF strips. It came out nice, and does work. Maybe this will help someone.
