Great guide. Really helpful.

I'm making my way through retrimming much of my interior, but I'm stuck on the B Pillars.
My material is a rather think tripe woven fabric that almost exactly matches the factory beige - problem is it's thickness is making it incredibly difficult to get around the curves at the top of the B pillar trim.

Any suggestions on how to get the material around the curve? Does heating up help it? Or can a professional stretch it?
