I work in advertising and the guest door with a sign to change the light cloth, but how to pull him well, I have seen some can be like a wood. How do you pull it?
It's called tight drawing! If there is no back iron, should be stretched like a drum face!
If there is a backboard, it should be like wallpaper! First to the side, then to the diagonal.
Then the side of the fixed side of the force, if that is the 100 square below the door, a person can fix!
