Pre-fabricated templates to construct variable-dimensioned containers

An apparatus, comprising:

• a sheet of a foldable material having edges that form a polygonal shape, a central portion having the polygonal shape concentric within the sheet, and a pattern of perforations through a surface of the sheet, wherein the pattern of perforations includes,
• a first polygon having the polygonal shape of the sheet, concentric within the edges of the sheet,
• multiple diagonal lines, wherein each diagonal line extends linearly between a respective vertex of the central portion of the sheet and a corresponding vertex of the sheet, and
• a set of first and second lines for each vertex of the central portion of the sheet and for each vertex of the first polygon, wherein each of the first lines extends from the respective vertex to an edge of the sheet that is adjacent to a corresponding vertex of the sheet, and wherein each of the second lines extend from the corresponding vertex to another edge of the sheet that is adjacent to the corresponding vertex of the sheet;
• wherein the pattern of perforations defines multiple selectable removable portions of the sheet and multiple corresponding selectable remaining portions of the sheet;
• wherein each selectable remaining portion of the sheet is configurable as a respective container having a corresponding one of multiple dimensions;
• and
• wherein each selectable remaining portion of the sheet includes triangular-shaped portions to overlap side-walls of the respective container.
