Hinging drywall apparatus and method

A drywall apparatus comprising:

• a finishing drywall liner;
• a framing drywall liner;
• a first gypsum-containing segment between the finishing drywall liner and the framing drywall liner;
• and
• a second gypsum-containing segment between the finishing drywall liner and the framing drywall liner, said first segment and second segment connected by a hinge formed from the finishing drywall liner and the framing drywall liner to allow an angle between the first segment and the second segment to vary, such that the hinge allows the first segment and the second segment to assume a flat position in which the first segment and the second segment are coplanar, wherein a) in the flat position, the framing drywall liner includes a groove having a longitudinal length running along the hinge, b) the hinge allows the first segment and the second segment to assume a corner position in which the first segment and the second segment form an angle therebetween of 90 degrees and c) the framing drywall liner is integral across the groove for most of the longitudinal length, further including additional grooves on either side of the grooves adapted to mate with a structure for mounting the framing drywall liner to a wall.
