I am thinking about sewing my own sun visors and replacing the wasted cardboard backers. Only thing is, I have no clue how to go about it. I will be using the same headliner material I am doing the headliner with. I am at a loss though as to where to get the cardboard or backer to make the visors from, and how to do the edges. Also, how do you get the vanity mirror off the passenger's side cleanly and then reattach it to the new visor when it is done? I have never done this, but am ready to try it to save a few bucks. I will be using my mom's 30+year old sewing machine if I can figure out how to make it work properly. It's out of adjustment and I have to fix it if I want to use it. Once again, there are no easy projects on my car....
