Construction of the Arch Frame
A strong frame provides some strength and shape to your arch doorway diy project. Begin with two identical curves of arches made of plywood or flexible board. These will be the side ribs of your arch. The wood blocks should be next attached between the two curves to maintain their even spacing. This thin structure is what is referred to as the skeleton which supports the arch surface.
Screw the frame to the doorway, ensuring that it is in a straight and level position. Strong frame makes your arch stand years and the frame will not sink and crack as the house settles.
The Curve of the Arch is formed.
It is time now to give life to your arch doorway diy shape by shaping the curve. Take strips of drywall or stretch board and cut them so they fit the frame of the arch. Bend the material slowly and with each passing, apply it to the curve and use screws to hold it in place. Work carefully to ensure that the board does not crack.

Some additional time of sanding would make your arch look smooth and polished and give you an impression that the arch has been made by hand and that it has been professionally made.
