Begin attachment of side wall upholstery
The upholstery has black dots suggesting where hole should be punched. I also looked over the bolt locations in a factory build aircraft. For now I made the holes that would go into rivnuts installed in the centre fuselage inside skin. Since I have not yet installed the latter, I can get access to the sound deadening and remove those sections, including the adhesive layer, and make the best possible rivnut installation.
