Ken’s Custom Embroidery – Antioch, CA Visit us at www.kensembroidery.com. We are a full service, one-stop embroidery and screen printing shop. We have been serving eastern Contra Costa County for over 10 years. We sell garments, as well as decorate them with your logo or special design. We specialize in high school letterman jackets, which we sell at very affordable prices! If you have a special design that you want to put on jackets or shirts, we can do that through a process called digitizing, which converts your design into an embroidery file which our computer-driven machinery can read and sew. Come to see us soon!
