OmnAvia Interiors, LLC out of NC. They had a very high quality sheepskin used for jets with many colors to choose from they were not cheap. They are FAA certified for aircraft if you care. I was very impressed with the skins. Only problem was my local shop destroyed them when they tried to make seat covers. I recommend you use someone who knows what they are doing when it’s finally time to sew your seats. I ended up asking Abby at Flightline Interiors to help me but abandoned the sheep skin design.
I did manage to have one skin I had as extra that is now used as an accent in my living room.
