Firecracker drawing as follows:

1.The first step first we draw a triangle, pay attention to the lines of the triangle do not draw too straight, to have a sense of arc. (This curvature is the focus) as shown:

2. The second step we then draw a rectangle below the triangle, and draw two thin lines below the rectangle, draw a sparkler shape. As shown in the picture:

3. In the third step we draw striped decorations on the firecracker and draw five-pointed stars on both sides of the firecracker. As shown in the picture:

4. The last step is to paint it, the top and bottom painted in red, the middle stripes painted yellow and greenish blue, the five-pointed star painted in color, as shown in the picture:
