Headliner pattern?

[The "A" Team]

Hi everyone, I'm starting to work on the interior of my '30 Coupe. I'm going to get new upholstery backing board for the panels since the old ones are falling apart, and I was wondering if there are any patterns for the headliner, especially where the "folds" are sewn. My wife and daughter are willing to sew them, but a pattern or other reference would be very helpful.

Thanks.

John
