Best Described by the originator:
The full cost was for a package of poster board at Staples — which is what, for me, felt remarkable about the run, it was dirt cheap, and took no time at all. But how did this come to be? I worked for a few years at Simon's Stamps, a custom rubber stamp shop in Massachusetts where they have a gorgeous 150-watt laser engraver, and 95% of the time they're making interoffice memo stamps on it. While employed by them, I started sticking around after work so as to figure out what else I could burn with it — no one else really knew what to do with the machine outside of running rubber and sign plastic through, using the automated program, with the material presets that came with it. The boss was hoping to expand his product base, and I sort of shifted my job from sales and typesetting to ordering material samples, making stuff and showing everyone else how to do what I was doing. After I moved on to a traditional design job at a newspaper, I remained with the stamp company as a part time consultant, with the provision that I be allowed to come in whenever and use the machine.
Always be on the lookout for your next opportunity.
