SHEET ASSEMBLY AND METHOD OF MANUFACTURING A SHEET ASSEMBLY
20180114459 · 2018-04-26 ·

A sheet assembly comprises a first grid comprising a first plurality of shapes on the sheet and a second grid comprising a second plurality of shapes on the sheet. The second plurality of shapes overlay the first plurality of shapes such that the second plurality of shapes are in a center of one or more squares defined by the first plurality of shapes. The first grid in combination with the second grid creates a template for the creation of one or more discrete components such as a list, a table, a chart and a graph. In some embodiments, the first grid comprises a plurality of crosshair shaped plus signs and the second grid comprises a plurality of dots. The two grid patterns are overlaid and offset from one another. The two patterns are offset such that the dots are located at the center of the squares defined by the crosshairs.
