Christy Ferer (Vidicom CEO) suggests penciling your stripe pattern on the space. Place the blue tape where you do not want the paint to go. Paint between the piece of tape. Wait a day before removing it. Remove tape gently so as not to chip the bordering paint.
Dilute acrylic paint for softer, more translucent stripes. Rag or sponge on the stripes by dipping cloth or sponge lightly into paint and dabbing on between the strips of tape. The tape can be placed in other patterns, suggests grids, triangles, or checks.
