Frosted glass window.
We have a small window in our attic en-suet made of frosted glass.
Yer 'tiz, up there.
The en-suet is very small, just enough room for a Thunderbox and twin sinks.
This is what the window looked like this morn with the sun shining obliquely upon it. Due to the small nature of the room it was very difficult to get a good shot. These are the best I could manage.
Hopefully you can see the pattern of tree branches.
This is another shot I took a couple of hours later, just to show how different it looked once the sun had moved round.
