I started in my basement printing with supplies I bought from Speedball. That was over thirty years ago and I just checked, they are still at it. You can still participate in the magic known as screenprinting for not much money if you have some enthusiasm.

Their website gives you everything you need to get started:

You can purchase the “Ultimate Screen Printing Kit.”  As it says on their site: “It is designed for the true screen printing enthusiast!” Go at it.
