A sheet member fastening system and kit, as well as methods of hanging sheet members on a framework for a wall or ceiling surface are described. Fastening members, comprising substantially flat members and corner members are usable to enable edges of standard sheet members, such as wallboard or the like, to be properly supported and attached adjacent one another by means of the fastening members. The use of the fastening members enables hanging of sheet members on the framework without cutting of the sheet members or measuring of the relationship of the sheet member to the underlying framework, except adjacent a corner of the wall/ceiling surface. The fastening members allow attachment of the edges when not positioned directly on a frame member to properly secure the edges relative to one another. The fastening members are made of a material to accept fastening devices such as screws, staples, nails or the like to secure the sheet members thereto.
