1. A method of making a multi-layer product, comprising the steps of:
applying an adhesive layer onto an exposed surface of a first layer, to form a multiple-layer construction including an applied adhesive layer having an exposed surface;
applying a patch material onto the exposed surface of the applied adhesive layer, using a coating or spraying process, to define an array of spaced apart patches, the patches being spaced apart from one another on the exposed surface of the applied adhesive layer, the array of patches defining discrete mesas of the patch material, each mesa being independently surrounded by the exposed surface of the applied adhesive layer; and
cutting at least the first layer to define pre-formed lines of separation defining an array of first portions, each first portion of the array of first portions being aligned with a respective one of the spaced apart patches of the array of patches.
