A method is provided of producing and assembling a multi-part surface-mountable physical-activity lamina for use in aiding or supplementing a physical-activity in a physical-activity environment. There is a step a] of providing a first graphic design model of the lamina; and b] segmenting the first graphic design model into a plurality of graphic design model portions. A step c] follows of arranging the graphic design model portions into a more compact second graphic design defining a reduced surface area; and then d] the second graphic design being applied to a lamina substrate having another surface area. The lamina substrate is then separated into lamina elements corresponding to the graphic design model portions, followed by a step e] of assembling the lamina elements onto a mounting surface at a physical-activity environment to form the surface-mountable physical-activity lamina.
