Paint all your nails one of your colors.
Place a small dab of your second color onto a piece of paper. I found that using a small amount and refreshing it for each nail helped prevent the dab from becoming too goo-like.
Dip the ball end of a sewing pin into your dab.
Stamp your nail with the pin. This works just like a stamp, just press semi-firmly and quickly. Dip the pin into your dab of polish again if necessary and place another dot next to the first. Continue dotting the tip of the nail.
Paint in the tip of the nail or any areas that were missed.
Let dry and apply top coat.
