A reverse molded fiberboard panel; a wainscot kit comprising a plurality of differently sized reverse molded panels, and a planar finishing or spacer panel, adapted to completely cover any size wall between a wall base board and a wall chair rail; and a method of reverse molding a loose cellulosic mat, in a single pressing step, to provide one or more relatively high density, raised panels without requiring preliminary pressing, or other pre-shaping step, such as scalping. The reverse-molded panels are molded in a conventional, multi-opening fiberboard press, in a single pressing step process, while achieving excellent transfer of mold detail (embossing fidelity) without visually noticeable fiber fracture.

What is claimed is: 1. A door, comprising: a structural support; and first and second composite wood door skins, each door skin having an interior surface secured to said structural support and an opposite exterior surface exteriorly disposed as an exterior surface of said door, at least one of said door skins comprising a major planar portion lying in a first plane, a planar panel portion lying in a second plane spaced from the first plane, and a contoured wall surrounding said planar panel portion and interconnecting and integral with said major planar portion and said planar panel portion, said door skin reverse molded with at least a portion of said contoured wall extending outwardly relative to said first plane and said exterior surface of the door in an exterior direction of the door, wherein said outwardly extending contoured wall portion has a lesser thickness than said major planar portion. 2. The door of claim 1, wherein said planar panel portion is disposed outwardly relative to said major planar portion. 3. The door of claim 1, wherein said contoured wall includes a first portion including a rounded top proximate said major planar portion and a second portion proximate said planar panel portion. 4. The door of claim 1, wherein said outwardly extending contoured wall portion includes an apex. 5. The door of claim 4, wherein said apex includes a rounded top. 6. The door of claim 5, wherein said contoured wall further comprises a plurality of raised planar steps interposed between said major planar portion and said rounded top. 7. The door of claim 1, wherein said contoured wall includes a first contoured portion adjacent said major planar portion and a second contoured portion adjacent said planar panel portion. 8. The door of claim 7, wherein said first contoured portion extends outwardly from said first plane and said second contoured portion extends inwardly relative to said first plane. 9. The door of claim 1, wherein said contoured wall extends outwardly from said first plane at an angle of about 25° to about 35°. 10. The door of claim 1, wherein said door skin comprises a plurality of planar panel portions, and wherein each one of said planar panel portions is rectangular. 11. The door of claim 1, wherein said contoured wall is rectangular in plan. 12. The door of claim 1, wherein said door skin is formed from at least forty percent by weight wood fiber selected from the group consisting of pine and fir. 13. The door of claim 1, wherein said door skin is formed of hardboard. 14. The door of claim 1, wherein the door skin is reverse molded from a mat of refined cellulosic fibers and sufficient binder to adhere the cellulosic fibers together into a structurally sound article having a specific gravity in the range of about 0.96 to about 1.08, said mat formed from at least 80% by weight fibrillated cellulosic fibers refined from wood chips, based on the total dry weight of the fibers in the mat. 15. The door of claim 1, wherein said outwardly extending contoured wall portion has a specific gravity that is greater than the specific gravity of said major planar portion. 16. The door of claim 15, wherein the specific gravity of said outwardly extending contoured wall portion is in a range of 1.02 to 1.08, and wherein the specific gravity of said major planar portion is in a range of 0.98 to 1.00. 17. A door, comprising: a structural support; and first and second composite wood door skins, each door skin having an interior surface secured to said structural support and an opposite exterior surface exteriorly disposed as an exterior surface of said door, at least one of said door skins comprising a major planar portion, a planar panel portion, and a contoured wall surrounding said planar panel portion and interconnecting and integral with said major planar portion and said planar panel portion, said door skin reverse molded to provide said contoured wall with an outwardly extending portion protruding outwardly from said major planar portion relative to said exterior surface of the door and a co-planar portion extending between said outwardly extending portion and said planar panel portion, said outwardly extending portion of said contoured wall having a lesser thickness than said major planar portion, said interior surface of said co-planar portion of said contoured wall being co-planar with said interior surface of said major planar portion. 18. The door skin of claim 17, wherein the door skin is reverse molded from a mat of refined cellulosic fibers and sufficient binder to adhere the cellulosic fibers together into a structurally sound article having a specific gravity in the range of about 0.96 to about 1.08, said mat formed from at least 80% by weight fibrillated cellulosic fibers refined from wood chips, based on the total dry weight of the fibers in the mat. 19. The door skin of claim 17, wherein said outwardly extending contoured wall portion has a specific gravity that is greater than the specific gravity of said major planar portion. 20. The door skin of claim 19, wherein the specific gravity of said outwardly extending contoured wall portion is in a range of 1.02 to 1.08, and wherein the specific gravity of said major planar portion is in a range of 0.98 to 1.00. 21. A door, comprising: a structural support; and first and second composite wood door skins, each door skin having an interior surface secured to said structural support and an opposite exterior surface exteriorly disposed as an exterior surface of said door, at least one of said door skins comprising a major planar portion lying in a first plane, a planar panel portion, and a contoured wall surrounding said planar panel portion and interconnecting and integral with said major planar portion and said planar panel portion, said door skin reverse molded to provide said contoured wall with an outwardly extending portion lying in a second plane disposed outwardly relative to the first plane and a co-planar portion lying in the first plane so that said interior surface of said co-planar portion is co-planar with said interior surface of said major planar portion, said outwardly extending portion of said contoured wall having a lesser thickness than said major planar portion. 22. The door skin of claim 21, wherein the door skin is reverse molded from a mat of refined cellulosic fibers and sufficient binder to adhere the cellulosic fibers together into a structurally sound article having a specific gravity in the range of about 0.96 to about 1.08, said mat formed from at least 80% by weight fibrillated cellulosic fibers refined from wood chips, based on the total dry weight of the fibers in the mat. 23. The door skin of claim 21, wherein said outwardly extending contoured wall portion has a specific gravity that is greater than the specific gravity of said major planar portion. 24. The door skin of claim 23, wherein the specific gravity of said outwardly extending contoured wall portion is in a range of 1.02 to 1.08, and wherein the specific gravity of said major planar portion is in a range of 0.98 to 1.00.
