Color applications for aerodynamic microstructures are disclosed herein. One disclosed example apparatus includes an aerodynamic microstructure of a vehicle, sub-microstructures superimposed on the aerodynamic microstructure, and a color application defined on or within the microstructure.

A product including a fabric layer is situated in a plastic bag such that at least a part of the fabric layer is aligned with a portion of a plastic sheet of the bag. An embossing tool is used to press the product and impress the embossing pattern into the fabric product, through the plastic sheet, as well as in the plastic sheet itself, at the same time. Perforations may be created by the embossing tool in certain sections of the product, such as the non-folded sections, and not in other sections. The perforations become an array of holes to create a mesh-like affect by stretching the fabric as the product is removed stretched from the package, used and washed. The tool also presses the plastic sheets together to seal the product in the package.

A formed sheet metal material and methods, tools and apparatus for forming the sheet metal material in which a pattern of projections and depressions are cold worked in a first portion and, simultaneously, indicia is embossed in a second portion of the sheet material. The cold worked portion is formed with the projections and depressions configured and distributed such that lines drawn on a surface of the formed sheet material between adjacent rows of projections and depressions are not rectilinear. The indicia is indicative of the alignment between the tools.
