From what people have told me, with a couple exceptions, the headliner texture should be the same as sun visors, indents with small 'random' raised lines in horizontal and longitudinal directions
The headliner sample I got from WU does not match that texture
I have bought other material from WU and think they are a fine company
I received samples from lots of places and the only one with close to the correct texture was from SMS fabrics in Portland OR
They matched the texture for a member here with a CSL, in black
After several months and a false start, they sent me the material in a very close (usable) color
The problem, when I was ready to have the pro install it, he said the material is too thick and heavy and it won't stay up
Maybe it would work if you had a non-sunroof car
The headliner in my car seems original based on the glue and foam but no way to know for sure
The pro thought it was original also
It does not have the raised lines, the indents are very similar but the background does not have the raised lines
It has a very fine 'leather' texture
The place in Belgium Lakewell or something like that has material very similar to that
