I used water glass, it's 62 by 132 cm and made to go in a door between the kitchen and the entrance hall and one for the living room door.
And here the window placed in the living room door.
Best picture I think. Kitchen door in the back and the living room door on the right.
Still on the workbench on a white board. This doesn't do the colours justice.
Really pleased with the soldering. :-)
Here you can see a little of the beautiful colours of the water glass.
