    Abstract: A method (100) of constructing a flexible object (20) formed of a plurality of mutually conjoined layers (22) is disclosed. A first outer layer (28), four intermediate layers (36), and a second outer layer (38) of substantially a fusible polyester sheet material woven of microfibers are obtained (110,124,130). The first outer layer (28) is positioned (144) over a work surface (24), the four intermediate layers (36) are positioned (148) over the first outer layer (28), and the second outer layer (38) is positioned (150) over the first outer layer (28) and intermediate layers (36). A laser cutting head (26) is configured (158) to be fusional for all of layers (28,36,38). A periphery (50) of the object (20) is then cut (164) through each of the layers (22) by substantially simultaneously moving the laser cutting head (26) relative to the layers (22), and coincidentally fusing (166) the peripheries (50) to form the object (20).
