Small muranese is awfully familiar. In sheds, in outside loos, in tiny, cast iron window frames.

Our stained glass panels and windows here seem to use a lot of Chance Pilkington textures I'm more familiar seeing in handkies, but we had to get a couple repaired after they got stood on by burglars on their way in (they didn't use the door).
It was very difficult to find the right textures and colours of flat glass for the repairs, and the lady artist(Liz Rowley) who did it for us made an excellent job of substitution where she had to.
The only old glass in external windows here is in the small back window, (now part of the new bathroom) which has a texture of fine vertical lines.
There was a right mish mash of old stuff in iron frames in the cottage. Including, I'm sure, one bit where two bits of glass were just pushed together side by side.
I'll see if I can find pics. (They've been replaced.)
