Screen printing is one of the most common ways of decorating clothing with a design. There’s a lot of setup and cleanup involved, but outside of that, it is very quick, easy, and inexpensive. You can incorporate multiple colours, but this increases the time, difficulty, and expense. We will keep it simple and use one colour.
Basically, your design needs to ultimately be printed out in BLACK and WHITE. Not greyscale. One colour of ink on one colour of material. The design needs to be printed as BLACK. You can apply whatever colour of ink you like after that.
You will design something that is made up of simple shapes and text. Using text and things like icons from The Noun Project or simple shape-based drawings would work.
You can design this on whatever software you wish (Photoshop, Illustrator, InDesign, etc.)
Set up your page to be 8.5 inches by 11 inches. You can decide whether it’s landscape or portrait.
Here are some examples of logos and designs that have worked well in the past:
