An idea comes to you. Most people would stop here and let it go, but you know ideas are elusive; they depart once they think they’re not needed, and they’ll find someone else to breathe life into them. So you start looking into making it happen.
You quickly realize it’s uncomfortably expensive to make the idea happen. The material is expensive, the expertise is even pricier. You could try to learn how to do it yourself, but that’ll take a fair amount of time as well.
You think smaller. Cheaper. Faster. Common formats that are right in front of you. You look for tricks that help you achieve just the essential effect, and nothing more.
Even when I was a kid, I couldn’t screen print t shirts, so I went to OfficeMax and bought the iron on stuff. Saved money up to buy the good ink.

It just depends on if you have the energy to do that.
