Welcome on board. I will try to help you to start quickly.
1) Planning
1.1.) Organize your designs
First thing first. Most important thing is your design. You need to decide which one of your masterpieces you would like to share with the world. This is the most difficult one. Don’t go crazy but do not be so fussy either. Buyers always would like to see options. Show them they have alternatives do not stick with only couple of designs.
1.2) Which printing technique?
We have two types of printing techniques.
1- Dye-sublimation All Over Printing
2- Direct To Garment
See our products page to see which product works better with which printing technique. http://alloverprint.it/print-on-demand-all-over-print-products/
1.3) Which product?
You can always (and probably) will start with t-shirts but we have different type of products too. http://alloverprint.it/print-on-demand-all-over-print-products/
