Anyone make their own interior

No experience with online course, but took a few quarters of upholstery class at a trade school about 20 years ago. Really enjoyed it and did a couple completes on my cars. Quite a bit to it if you are going to do seats, door panels, headliners and convertible tops. My experience would be that you might learn something online, but it would be no where enough to really do a complete job like you would learn hands on in-class from an experienced instructor, plus you get to use their equipment.
