The left hand (board edge) mark of the paper template is aligned with the mark just made along the spine edge of the board, and the other marks of the template are transcribed to the cloth. The right hand board is aligned with the other (outer) board edge mark of the template, and the cloth is trimmed 1" to the board's right hand edge. The cloth is now trimmed to final overall dimensions. The boards are affixed to the cloth with a 1" margin of cloth on all four sides. PVA mixture is used for this and is applied to the boards, not the cloth.
