The technique takes a little practice and some getting use to. Your first stencil caps will help you develop custom lines and dots. Once you've made few functional stencil shapes, redraw them onto another lid. The master cap should work only with the spray tip it's designed for, you may want to write the name of the tip onto the lid. In this case a grey dot will conserve paint, reduce mist and focus the spray hardness. Here are the two original caps, a forward angle double point and a star stamp. Since I know both these shapes work, they'll be transferred to the master cap. The stencil cut away area is always located a little below the atomizer (grey dot in this case) on the spray tip.
