I am an expert in all kinds of interior and exterior paintings.
To design is very easy for me.
Before the the painting or any design you need take some steps like mixing the paint well.
Firstly i painted the ceiling with white paint, and i painted the background of the wall with white paint
This the wall before the design
i need to wait for some minutes to dry after that i started to lay the paper tape on the background and started painting it my roller and brush
for the television wall.
This is what we called spongy design.
After the work finished.
