The center of the spine cloth is marked, and the spine piece of the board is affixed to the cloth, centered both ways, using PVA mixture. A spacer template is made by gluing together two pieces of grey/white board. The front and back boards are glued to the cloth, positioned so that they are each the thickness of the spacer template away from the spine piece. The boards and the spine piece are all aligned against a straight-edge (not shown).
