Are you sure it isnt 3/16? The 1/8 inch shows every imperfection under it.

Ya the 3/16 made the sunroof sun shad slide hard. And the pattern & color match was best with the 1/8

It’s a 2006 VW Beetle 2.5 with sunroof

Ive have gone over the 3/16 with 1/8 and that hides a lot

Like Robert said the 1/8" shows all the imperfections. For some common colors you can buy 3/16" to use on the headliner and matching 1/8" for the sunroof shade

I always buy 1/8 headliner when doing sunroof and headliner. Most boards are pretty smooth and come with 1/8 now. 1/ 8 isn't any harder to work with than the thicker foam back IMO. Wait until you get a vw or bmw guy that wants suede headliner lol. Did a few of those. Suede headliner has No stretch and those boards have contours that require headliner to have stretch to it. And for anyone who hasn't had a land rover or range rover, make sure to measure the width at the time of your estimate. Some of those require 65 in material. And irs sometimes hard to get the color match.
