Cutting out the cloth requires a good bit of precision to cover every bit of your tray neatly and properly. In a single-wall clamshell box, the cloth (or other covering material) is the strength of the tray. Cut your selected cloth with the selvage running around the tray, parallel with the tray walls’ grain. Mark up a margin along the two edges with a set of dividers (this covers the bottom of the base and the tray edge turn in). Pitch your dry tray on the marks, and tightly turning the tray along the bottom margin lines, mark the top and edges of the tray.
