With all of the marvels of the internet there are some things you can do that in the past was either financially impossible or tremendous work.
The one thing I am pointing out is how easy it is to self publish a book. In my case it was creating a hard copy of all of my stained glass patterns.
The printing company Lulu.com has made it possible for authors to create books of their work and offer them for sale without printing minimums. Beyond books they also have other templates for calendars, posters and many other format medias.
I strongly recommend anybody with an idea or artistic content to look into self publishing.
