Screen Printing. Create a stencil of your design using screen printing techniques. Place the stencil on the T-shirt and secure it. Apply fabric ink over the stencil using a squeegee, ensuring even coverage. carefully lift the stencil away and allow the ink to dry according to the ink manufacturer’s instruction.
Hand Painting. Place a cardboard inside the T-shirt to prevent the paint from bleeding to the other side. Use fabric paint and brushes or sponges to apply your design directly onto the T-shirt. Allow the paint to dry completely, then heat-set it according to the manufacturer’s instructions (usually ironing the back of the design).
