Request: Seat upholstery (the rest)

I know there's DIYs available for recovering the bottom seat inserts, and one for the back seat inserts, but how about one for the rest of the seats?

i was lookin to change the stitching color and fix the damage to my drivers seat, which is the stitching on the bolster that has worn away.

can anybody make an informative DIY on doing this? specifically i'd be looking for what kind of thread to use with the Side impact airbags and what kind of thread to use in general.
