I know this thread is more or less dead, but it shouldn't be! This is an excellent write up! Covers 100% of the job and Shutter is 100% right about the difficult sections. My visors turned out amazing, can't wait to tackle the headliner!
One word of advice for anyone willing to try this: Make sure your fabric is crease-free. Iron it out with a little steam, low heat(THIN FABRIC). If you can't iron, ask your girlfriend. If she can't iron, fire her and get a new one.
