I've been thinking about picking up a new 'indoor' hobby for the winter - something I haven't tried before.  I decided to give leather tooling a try.  As an experiment, today I tried to make a patch for my backpack.  I still need to stain and seal it, but I think it came out half-decent.  This winter I think I am going to try to make a few things when it is too cold to go out to the workshop - a belt, a wallet, and maybe a ukulele strap.  The kids have shown some interest in giving it a try too.
