New test question: which side is up on the felt strips that install length wise on either side of the sunroof.

I sources some OEM felt strips and they have a flat side without very much felt. The other side has a thickness to it and most of the fuzzy felt is on that side.

I think the thicker, fuzzier side is supposed to be up, meaning facing towards the sky, but I'm not totally sure since my originals were so deteriorated I couldn't tell.
