I'm finding very little (more like none) DIY upholstery links.
It seems we do everything else but, few if any, are doing their interiors.
If I could find a reasonable source for the material I might be up to having a go at it. When I was young I used to watch my mom sew and picked up a few things. The most important being "don't use my good scissors" she used to yell. My dad had a favorite hammer I was not to touch also. I understand now.

There's lots of 'rust' discussion in the restoration forum. Interior resto threads...nil. I'm I the only one needing interior work on a 28 yr old car?

At the NTX GTG Rashakor showed me where he had replaced a seat panel using some material he obtained at a local fabric place. I agree with him on if it can be taken apart... we should be able to put it back together.
