I've got my leadlight window installed now. It's just held in place in front of the existing glass with some rimu beading, which simplifies matters enormously — I don't have to worry about it being weathertight (I suspect it's not), if I want to, I can dismount it pretty easily, and it's quite well protected from damage from outside.
Now I have to make one for the other side. I don't want a straight mirror-image of the first, but I do want it to look like they go as a pair. I'll be using the same colours and textures of glass, with a similar sort of design.
I'd really like a much nicer door as well, but that may never happen.
