ABSTRACT:
A method of integrating first and second skins into a contiguous cover layer by: providing a first skin with a first surface to be exposed and an opposite backing surface, with the first skin having an offset edge defining a first corner with the exposed part of the first surface; providing a second skin with a second surface to be exposed and an opposite backing surface, with the second skin having an offset edge defining a second corner with the exposed part of the second surface; placing a mold element/partition between the first and second offset skin edges to maintain a space between at least a part of the first and second offset skin edges; pouring a flowable foundation material that will harden against the backing surfaces of the first and second skins so that the hardened foundation material exerts a force tending to urge the first and second corners towards each other; and removing the mold element/partition from between the first and second offset skin edges so that the space between the parts of the first and second offset skin edges diminishes to cause the first and second corners to move closer to each other than they are with the mold element in place.
