I was tasked with creating event credentials for OPTIMA Batteries a few years back. The actual carbon fiber tags were already printed and cut. So instead of creating a clear decal which had been done the previous year, I created the decal to be printed directly on the tag itself. Luckily I had friends at Digital Hub Chicago that could print directly onto any material. When the event was over I got one of the last ones. People were offering a pretty large chunk of change for one of these.
