I replaced the headliner in my E34 with material (from headlinerkits aka wlsheadliners) 2 years ago. The material only stretches in one direction so the fit around the sunroof was bad. At 1/4", it's too thick for the sunroof as well.
Now It's time for the wife's E34. Where can I get thinner materal that stretches in both directions?
Thanks
