To capture the realistic texture of leather when drawing boxing gloves, it's essential to pay attention to the small details. Start by studying reference images or even real boxing gloves to understand the nuances of the leather's texture. Use a combination of light and dark shading techniques, such as cross-hatching or stippling, to create the appearance of grainy leather. Experiment with different pencil pressures and strokes to mimic the varying smooth and rough areas of the material. Remember to observe how light interacts with the surface, as highlights and shadows can greatly enhance the realism of the leather texture.
