I claim: 1. A method including the steps of: providing a pliable, thin metal plate; adhering a length of wire to a first face of the metal plate, the wire having a pair of ends; providing an insulation product comprising multicellular bubble film for trapping insulative gases; and, a layer of polyethelene coating over the multicellular bubble film; and, a thin layer of foil on a top face; engaging the top face of the insulation product into contact with the first face and the wire, thereby positioning the wire between the first face of the metal plate and the top face of the insulation product; enveloping the plate and insulation product within a removable cover. 2. The method as in claim 1, further comprising the steps of connecting a battery to each of the ends of the wire. 3. The method as in claim 1, wherein the adhering step includes the steps of: positioning a first layer of two-sided tape on the first face of the metal plate; and, pressing the wire onto the two-sided tape. 4. The method as in claim 3, further comprising the step of positioning a second layer of two-sided tape on top of the first layer. 5. The method as in claim 4, wherein the wire is positioned between the first and second layers of two-sided tape. 6. The method as in claim 1, further comprising the steps of positioning a first double-layer of two-sided tape on the first face of the plate; and, placing the wire onto the first double-layer of two-sided tape; positioning a second double-layer of two-sided tape on top of the first double-layer of two-sided tape. 7. The method as in claim 1, further comprising the step of positioning the wire so that each of the pair of ends extends outwardly from the metal plate, and connecting each of the ends to a respective terminal of a battery. 8. The method as in claim 1, further comprising the steps of connecting the ends of the wire to a battery; and, positioning a switch adjacent an edge of the thin metal plate; and, selectively activating the spot warming device by tripping the switch. 9. The method as in claim 8, wherein the switch is a three-way switch having a first position wherein the switch creates an open circuit; and, a second position wherein the switch creates a circuit wherein current is directed through half of the wire; and, a third position wherein the switch creates a circuit wherein current is directed through an entire length of the wire. 10. The method as in claim 1, further comprising the step of selecting the metal plate of aluminum. 11. The method as in claim 2, further comprising the step of enveloping the battery within the cover. 12. The method as in claim 2, further comprising the step of providing a fuse in electrical communication with the battery and the wire; and, configuring the fuse to create an open circuit when the device reaches a selected temperature. 13. A device comprising: a pliable, thin metal plate; a length of wire having a pair of ends, the wire adhered to a first face of the metal plate; insulation product positioned to engage both the first face and the wire, the insulation product comprising multicellular plastic bubble film for trapping insulative gases, a polyethylene coating over the plastic film, and a thin layer of foil covering a top face of the insulation product; a cover enveloping the metal plate, wire, and insulation product; a first layer of two sided tape adhered to the first face of the thin metal plate; a second layer of two sided tape adhered to the insulation product; wherein the wire is positioned between the first and second layers of two-sided tape. 14. The device as in claim 13, further comprising a first double-layer of two-sided tape adhered to the first face of the metal plate; a second double-layer of two-sided tape on top of the first double-layer of two-sided tape; and wherein, the wire is positioned between the first double layer and the second double layer. 15. The device as in claim 13, further comprising a battery; wherein, the wire is positioned so tat each of its pair of ends extends outwardly from the metal plate, and wherein, the pair of ends is connected to respective terminals of the battery. 16. The device as in claim 15, further comprising a three-way switch positioned adjacent an edge of the metal plate, the switch is a three-way switch having a first position wherein the switch creates an open circuit; and, a second position wherein the switch creates a circuit wherein current is directed through half of the wire; and, a third position wherein the switch creates a circuit wherein current is directed through an entire length of the wire.
