A process and the resulting uniquely configured product called “Buck Shot Blues”. The base product is a fabric such as denim that has been processed and altered to accomplish an appearance that the fabric has been “blasted” by buck shot or small metal pellets. The resultant fabric has a plurality of holes or apertures in a “blast pattern” that is either specific or random. The holes or apertures after processing are “frayed” from the penetration of the blast elements. The manner of production includes a number of methods, from a simple blast scheme to more complex production processes. An alternative computer controlled manufacturing process is also provided where the individual interacts with the process that produces his garment.
