This option is great if you have an idea of what you want, but don’t have a lot of time. (You can even upload basic artwork to one of the vendors above and add additional elements with their tools.) This semi-custom option requires a little more time and work but gives most designers the control they want when working on a shirt design. One more option when it comes to free t-shirt design tools is to download a template, customize it in whatever tool you prefer, and then upload it to a printer.
