Recently had my aging leather seats repaired. Mine were beyond repair and tears formed everywhere. After doing much research I ended up at an upholstery that advertised car leather re-covering as their specialty. My next choice was buying a replacement OEM leather seat cover outright and having them install it. Their seat repair, where they replaced entire sections cost $40 less than a new full cover.
The areas on the seat that were part of the side airbags, they didn't touch, understandably to avoid lawsuits. They told me to
buy a replacement OEM cover online. Luckily the tear on that part of the seat is similar size to yours. They also told me since a small tear becomes a big one pretty quick, that I could just use strong duct tape in the meantime.
That surprised me... the duct tape part. I asked them if they had any they'd recommend. They stuck one on my car that they had in the shop. It definitely is a thicker variety and super sticky. Wish I could tell you more. I did look at the roll saw no branding. 8 months later, it is holding up well.
