could anyone recommend a solution for keeping hands warm? Not least in preparation for actually playing guitar, but also for more general use. I sit at my desk all day long and my hands are perpetually freezing cold, to the extent that it's painful rather than just uncomfortable. There are lots of electric handwarmers on Amazon, plus some disposable stuff and things that go in the microwave. The latter wouldn't work for me, for lack of a microwave.
I'd be grateful for any tips and experiences fretboarders may have to share.
