The standard box size allows them to be easily stacked, and the boxes are big enough to contain most items, but small enough to be easily manipulated. The standard tray size allows trays to be swapped between boxes, so just the required materials can be taken to a game.

• Glue the cardboard together with plenty of PVA glue. Weight pieces down while they dry, so that the two pieces that you are gluing are pressed together firmly. Alternatively stick pins through the cardboard.
• Make some dividers the full height of the tray, particularly in the middle of the long side.
• When making a tray for different shaped bits of scenery, write a serial number on the underside of the scenery piece and in the tray so you know where to put bits when packing up.
• Strengthen the corners of the trays with a piece of cardboard, about an inch wide, glued at a 45 degree angle.
• Cover the outside corners of the trays with duct tape, again to strengthen them.
• Make sure there is a piece of partition which can be used to lift the tray out of the box. This should be large, fairly central and reinforced by other pieces of cardboard at right angles.
