Silk painting is similar to watercolor in it's basic techniques, i.e. washes and wet into wet. In this piece (which will be a tallis - Jewish prayer shawl) I'm going to use washes that change in color or intensity. I've painted the sun starting in it's middle with yellow, and as I've gone to the outer edge I've changed to orange-gold. The colors continue to blend with each other long after I've moved on to another section.
For the olive green color, I'm starting with a small brush because I have to work around the Hebrew lettering that borders the sun. The gutta I've put on the letters will keep the olive color out, but I need to be careful not to flood the area as that would send color over the gutta instead of just up to it.
I've lined up various values of my olive green colors in these cups, and will gradually change from on to the other as I paint the large field of color. Keep the paint nice and juicy, and overlap your strokes for the smoothest transition possible. Don't answer the phone - you gotta keep it going until you've finished the entire shape.
