The additional layer includes at least first and second discrete portions positioned along the longitudinal direction. The at least first and second discrete portions are spaced apart from each other along the longitudinal direction. The portions are constructed of the same base sheet material and the first portion at least partially defines an opening therein with an opening inner edge. The second portion is of a shape mated to fit along its periphery edge, at least partially within the opening. The second portion is of a shape complementary with the opening shape. Edges of the first and second portion are complementary, the inner edge of the first portion being complementary with the periphery edge of the second portion.
