I love print-on-demand products. They provide me the power to create and wear unique products. But the biggest advantage for me is that with print-on-demand I can create matching products with the same design.
Print-on-demand is a business model where you sell your own custom designs on products like t-shirts, mugs, posters, and more. You don't have to worry about inventory, production, or shipping - there are websites offering this service for you and one of them is Printful.
