Always difficult to start a new window I think. Not that I have that much experience, but making a start, trying to decide where the leadstrips go as I find that very important as this can make all the difference how the end result looks.

I decided to use for the bottom and sides the brown colour. Not sure about the top. I'll decide when I get there :-)
The type of glass I will mostly use for these windows is so called water glass.
