I'm a woodworker from way back with an extensive shop of tools and I have some upholstery experience, as well as a good amount of amp and speaker covering experience, so I think I could pull it off quite nicely. I've also been playing guitar for 35+ years, and have gone through more than my fair share of guitars and cases, so I know what there is to love/hate about them. Not that I wouldn't like to read what someone else has to say about doing such a thing. Every project is different, and has different considerations. The only reason I haven't done a custom case so far is I've always either lived with what came with an instrument or bought something better, which has been easy since I'm something of a right-handed traditionalist so I've never needed a custom case. Right-handed Strat and Les Paul/SG-style guitars are fairly common.
