From website: Apply base coat and 2 top coats (white works best). Let dry completely! Use different color Sharpies to color in blocks of color. Use any size brush and dip it in acetone. Too dry and it won't work, too wet and the acetone will flood the nails/cuticle area and take off polish. Dab it all over the nail and wipe off the brush and re-dip every couple of times. I probably dabbed the brush on the nail 5 times.Give it a couple minutes and then add your top coat!
