I wouldn’t call it faint, it looks like corduroy in this image. I wonder if these are the same stripes I was seeing on tile in My first Laser tile - #110 by chris1, and what explains the difference between my results and @YawString’s.
The pattern is unfortunately very noticeable on something like My first Laser tile - #103 by chris1 and looks more like an inkjet printer with a clogged nozzle than a cool texture.
