Then we draw the second party.

Now we need to draw an arrow. For convenience you a dung to take a ruler and to put on a diagonal. One party of an arrow looks out outside, a point of a puncture can independently choose, I chose exactly on a diagonal of heart and if to take visually, it will be a half of a half, i.e. ¼. You can make that the arrow to leave the middle, for example. The end of an arrow leaves behind therefore only the part of an arrow is visible to us. We draw a tip and feathers.

We paint over heart in red color and the heart pierced with an arrow it is ready.
