I recently bought a used Consew 225 sewing machine from a local who no longer used it. I'd been hand sewing everything and I know nothing about sewing machines. So my question is what kind of oil should I use? And how's the best way to clean one of these? It's been sitting in a dusty barn for a few years. Thanks for any help

Are these still available?

I know this question has been asked here a thousand times. I've used the search function and researches it a lot. But now I'm gonna go ahead and ask: In your opinion what are some good saddle making schools to attend? I'm compiling a list to research. Studying under a local maker really isn't an option. Just hoping to get the most of my time at one. Thanks in advance for any suggestions!
