Carpets must be relatively easy otherwise re-upholstery of cockpits would be impossible. Nobody is going to buy whole new seats etc from the aircraft manufacturer. And the flammability due diligence is discharged by obtaining a specific certificate for the material. The actual work can be junk.
This thing is different.

Well, no, I would say that CS-STAN-103a allows you to make your own,
Which part of the text you quote in your view requires that you produce the part by yourself?
I don’t think carpets and other non-structural cosmetic interior trim are any different in the eyes of FAA.
These cosmetic items would be installed on a logbook entry (minor mod) and who produced them is irrelevant. The Owner Produced route is different and applicable to non-cosmetic parts (any) manufactured by either the aircraft owner or at his direction, supervised by him. Those have to be manufactured to design data, which is why e.g. the availability of original drawings is useful.
