First Screen Printed T Shirt Sale

Have been practicing screen printing for a while and the other day I decided it was time to start selling some of my designs online. I ordered some blank tees and put up a few listings on a local website with mock ups of the designs. The next day I had a sale so I prepared the screen and printed the t shirt. I have been doing print on demand for a while now and thought it would be cool to start printing some t shirts and selling them in my local country where print on demand isn't a thing also the profit margins are higher but obviously there is more work involved so they both have their cons and pros.
