If you are good at drawing, you can draw directly, or you can draw a sketch on a T-shirt and color it with Bingtin pigment.

If equipment is used, it is as follows:

Computer, small color inkjet printer, ironing machine, transfer paper.

First, make a pattern on the computer, then print it on the transfer paper with the color jet machine, and directly print it on the T-shirt with the ironing machine.
