Place your freshly painted white furniture in a well-ventilated space over plastic sheeting.
Pick up a small amount of red paint on a stiff brush and paint around spindle creases, carvings, corners and joints. Use a rag to wipe off most of the paint. It's desirable for a trace of red to come through behind your metallic paint. The red should be heaviest in the corners and creases and just a faint trace on the larger flat surfaces of the furniture. Paint the entire piece and rub off the right amount to achieve the look you want.
Repeat the process with a metallic paint. Metallic is often a looser paint that will tend to stick and shine more easily than conventional paints. Work your rag to get exactly the amount of metallic you want. Paint the entire piece and rub off the areas you want to remain the most white.
Go over the furniture with a fine-tip marker. Make small dots to look like aging and patina. Less is more. A brown marker often works well.
