Car Leather Upholstery | Custom Auto Leather Interiors by Katzkin

 

Sorry if this isn't helpful but, if you smoke in the car, or let people smoke in the car, why not just patch it? I say that because the upholstery is going to get kinda messed up from the smoke anyway so just wait until you eventually sell the car before replacing the fabric. I'm not saying that in a snarky way, it just seems a waste to spend so much when it could happen again.

 

The smoking in the car was a one-time deal, and my mistake for allowing it to happen. The fabric is definitely getting replaced and fixed ASAP, just looking for the most cost-effective method.

 

I'd talk to a bodyshop then and ask if they can recommend a fabric person. When I did bodywork we had an upholstery guy we'd out-source our repairs and re-upholstery work to (most shops do). They are pretty cheap and because they do this all day, they have a lot of experience. I think you might be able to get that thing hidden for very cheap. Being that it's in a less conspicuous spot (near a seam) works in your favor. The fact that it looks like a thread came loose, does not.
