These are slightly easier than the tazhib illuminated domes to prepare; essentially they are just grids.
Above is the Turquoise dome, which is traditional brickwork.
Make sure that the vertical lines of the bricks match each other as they skip lines, meaning they are not all over the place but neat looking.
I drew the initial pencil lines with a straightedge and then did the ink lines freehand. You could also use a straightedge for these. I wanted to use it as a kind of practice. I don't recommend doing the entire thing freehand.
The Black dome. A square grid, again drawn with a pencil and straightedge initially and then freehand. Some wobbles and sunscreen grease so watch out! Anyway we can correct these all later and it gives us the initial grid off of which to work and colour.
Again adapt to your preferred dome shape that hopefully you've drawn yourself; you could also draw a variety of dome shapes; I am sticking to my favourite onion dome shape.
