Methods of Using Preformed Nanotubes to Make Carbon Nanotube films Layers, Fabrics, Ribbons, elements and Articles are disclosed. To make various articles, certain embodiments provide a substrate (12). Preformed nanotubes are applied to a surface of the substrate to create a non-woven fabric of carbon nanotubes. Portions of the non-woven fabric (54) are selectively removed according to a defined pattern to create the article. To make a nanofabric, a substrate is provide. Preformed nanotubes are applied to a surface of the substrate to create a non-woven fabric of carbon nanotubes wherein the non-woven fabric is substantially uniform density.
