After the Software, What Else?

Beyond the less tangible things like ideas, inspiration, and talent, by definition you need software to do desktop publishing. What else? Fonts, templates, images, a printer, paper? Which are essential and which are possibly optional? I've compiled a list of the things you need to do desktop publishing. Some apply to everyone. Some are only really used by professional graphic designers (although anyone could make use of them).

What are your favorite desktop publishing extras? If you were helping someone else get started doing desktop publishing, describe the supplies (software, hardware, or otherwise) that you consider essential or very, very worthwhile. Use this Reader Response form to tell us what supplies you consider must-haves and why.
