Stipple and Rag-off the Wall
Still using the same brush, immediately begin stippling over the wet mixture. To do this, "pounce" the end of the brush up and down over the entire area. Use a cotton rag to begin the ragging-off process. First fold the cloth in one hand so that all the ends are tucked in (otherwise they would drag in the paint and spoil the effect). Then apply the cloth to the painted area and pick it straight up, moving some of the paint off. Continue over the entire area, turning the cloth as you work so that you're always using a new part of its surface. As the rag absorbs the paint, keep refolding it to expose more clean cloth. Try to work in circular motions as you rag.
