My late grandfather’s business was all about paint. He draws souvenir pictures for American soldiers after the World War II. He paints signboards for movies and for small stores. He also does customize printing on t-shirts, basketball jerseys and more. He would manually cut-out the designs by himself to be able to do silk screen printing. It was tedious and requires a lot of time. So, if you need a work to be done, you have to order a month before to allow time for mass production.
But those were the thing of the past; today you can easily order custom t-shirts for your family reunions, church events, school activities, club uniforms and more with a click of a mouse Yup, that is so true! I just recently came across an online shop where you can create the designs by yourself using their studio. After creating your design, you can automatically place your order and wait for the t-shirts to be shipped. They also accept custom embroidery, all at a very affordable price.
Customs shirst as giveaways is a great idea. Me and my bro used to do this as a hobby before just for fun. Its a tiring work, requires patient.
