Due to lack of materials, I was left with no other choice but to use the conventional method of paint brush. I got myself acrylic and textile paint which is usually used for silk screening but instead of making out a stencil, aside from being part of this art group in school who are into mural and canvas painting that time, I was able to practice my freehand drawing skill and decided to try freehand brush painting.
One good thing and I can say advantage the paint brush method has over the smooth airbrush painting is the brush strokes shown on the design. I find airbrush artworks flat and lack depth compared to the brush stroke you would be able to produce using this method.
Step 1: WHAT YOU NEED
2) Textile paint and acrylic for achieving varieties of colors. I just bought myself 5 textile colors namely: RED, BLUE, YELLOW, WHITE, BLACK; and a set of acrylic just for mixing to achieve more colors. Bear in mind that you should know how to mix paint and colors, just about the basics of color mixing. You can always use the trial and error method for color mixing until you achieve the desired shade or consult this website for more information.
3) Paint brush of various sizes (000, then 00, 0, 1, 2, and up) which will vary according to the measurement of your design.
4) Mixing plate, containers, for mixing the paint.
5) Any measurement tool: T-square, Ruler, Tape Measure.
6) Pencil or tailors chalk for drawing the outline.
7) Any hard material that would fit inside the jeans and shirt like chopping board or thin drawing wood board.
8) Design pattern.
9) Freehand drawing skill.
Step 2: Prepare the T-shirt.
Step 3: Secure the Drawing Board Inside the Shirt.
Step 4: You May Proceed to Drawing the Outline With a Pencil or Tailor's Chalk or Directly Painting It Over.
However for other designs, what I usually do is I draw a grid on my pattern so that I have a guide to applying the design on to the t-shirt, like what was explained in this link.
You may draw the grid directly to the t-shirt to ensure that your proportions and layout in a drawing are correct. When drawing anime characters, I usually start with the eyes. You can check out this site for more information.
Step 5: Continue on Painting and Playing With the Colors.
The brush size varies on the thickness of the outlines and the fill in objects. For outlines, I usually use the thinnest brush available, for filling depends on how big the object I'm going to fill in with colors.
