I have an old black tolex case and I threw away one of the pieces of padding because I didn't need it with the guitar I was using it with. I need it back though. It's brown fur-type lining. I also need a piece of foam to wrap it around. I've searched around but nobody seems to carry any case parts except latches and handles. Who sells lining materials? Do I need to try a fabric store? Anything to look out for with a nitro finish?
