Who doesn't like Process?

This is not a step-by-step how-to, just a few notes about how I happen to do things.

Doing your own printing is fun if you enjoy hands-on things, doesn't cost much, and lets you do a lot of per-print customization if you want, with different colors, streaks, multiple prints... but can also take a lot of time. It's really only worth it if you enjoy the process. If you just want to get a t-shirt made with minimal effort, there are iron-on sheets that go in a desktop printer, or there are many companies with web sites that you can pay to print your custom images on a t-shirt.

Have fun.
