Material preparation: paper, pencils and colored pens.

1, draw a rectangle in the middle of the paper and draw a separation line in the middle.

2. Draw two semicircles on the top of the rectangle.

3. Cross and extend downward along the wide side of the rectangle.

When the two lines intersect, it becomes the lower half of the heart.

5. Stroke along the already drawn shape with a colored pen.

6. After drawing the heart, wipe off the traces of pencil backing.

7. Finally, draw a color in the middle of the heart, and the heart will be drawn.

Techniques for drawing heart-shaped patterns:

1. Use compasses and rulers.

First draw two circles of equal size with compasses, then draw two straight lines perpendicular to the circles with straightedge, and divide the two circles into four parts. Next, draw a small square at the intersection of the two circles. The center of this small square is the apex of the heart. Finally, draw an arc on the four corners of the small square, and connect the sides of the arc with the small square to get a complete heart.

2. Free drawing method.

Draw some simple patterns by hand, such as two circles or semicircles, and then connect them with hand-drawn or mathematical tools and adjust them until you draw the desired heart-shaped pattern.

3. Use computer drawing software.

If you are not good at hand drawing, or want a more accurate heart-shaped pattern, you can use computer drawing software to make it. First, choose the canvas size and color in the software, and then use the circle tool in the toolbar to draw two circles.

Then draw two straight lines perpendicular to the circle with the straight line tool and divide the two circles into four parts. Then draw arcs on the four corners of the small square, and finally connect the arcs with the sides of the small square to get a complete heart shape.
