I don't do this very often but I googled 'stained glass blog' and, lo and behold, found another stained glass artist doing a blog - called Light Made Solid by an artist named Peter Boucher out of the Pittsburgh area. Interesting to read another blog by a someone working in the field. It's been a year doing this blog and this is the first one I've seen.
He's got a sketch section, which is rare for SG sites. I like this sketch in particular.
