I have a large (3.5") Forstner bit that has lost its edge. Is there a
DIY way to sharpen it, or is this something that must be done by a
professional? It looks like I might be able to hone the teeth and the
knife edges, but I'd like to hear what you folks have to say about it
before I do.

Thanks.

I've not (yet) needed to sharpen a Forstner bit, but Rockler has a kit
of sharpening tools and instructions for $18:
