Upholstery Question: Door Panel Pocket

I'm sure I've seen it done but can't seem to find it now. How do you make a pocket on a door panel? I'm doing my own upholstery work and want to add map pockets to the door panels.
Thanks

 

Anyone? I'll ask in the upholstery group as well.

 

The panel backing board must be a good one,stiff,so when cord for top of pocket is pulled through a hole at end of each side of top of pocket and knoted or stapled or both, it can take the load that happens when used.
There a few ways of doing the design.

 

Best pockets are not elastic or corded edge but have a fold down flap and snap or velcro closure.

 

Would I cut slits in the vinyl on the panel or just sew the pocket directly on top of it?
