Experimenting with putting texture on Maya's dress. I'm using rows of light and dark dots to give it the texture of woven heavy yarn - dark dots for the 'holes' between the stitches, and light dots for the yarn. The light dots go slightly above and offset from the dark dots to make a row of stitches. I'm not sure it really works, but I don't hate it and I'm going to finish it out. I've only done the top two thirds of the front of her dress so far.
I'm putting in highlight areas by using lighter colors for the light dots. For the shadows, I'm using darker shades for both the light and dark dots, and then glazing in some shading like normal over the dots.
