Just to add to what
@SNLC mentioned about the pattern hiding under the felt, I happen to be in the process of re-doing my headliner because the SFPO decided it would be a great idea to paint the headliner black on a windy day with only 1/2 a can of paint. My only option was to re-cover the headliner. I also ordered more fabric to do the door pillar garnishes. I am not completely sold on the result so I may, at some time in future remove the new covering and spend a day with a can of acetone and bring them back to basic plastic.
The photo below shows a little of what lies beneath the felt. The material in the background is my new headliner material - the color match is almost perfect.
