Step one:
First draw a pointed shape to make the nose of the paper airplane.
Step 2:
Draw another narrower, pointed shape inside.
Step 3:
Connect them with a horizontal line, being careful not to connect them in the middle.
Step 4:
Draw a sharp angle downwards in the middle and a small line upwards, paying attention to the position.
Step 5:
A paper airplane is too lonely. Use the same method to draw another paper airplane.
Step Six:
Add speed lines to the back of the paper airplane to give it the feeling of flying.
Step 7:
Finally, just paint the painted paper airplane with beautiful colors.
