Oooooh! I watched first few minutes; this is a must see for me! Thank you!
I thought it might be a bit elementary for you but it’s a great series that I really enjoy. As a craftsman I like to watch people discovering a craft. It’s also kind of interesting that the series concentrates on conservation. It might be something you might think of exploring. I’m sure there are folks around here in the states (although not many) who restore old glass in churches. You might think of seeking them out.
Anyways, I hope it gives you some inspiration.
