Step one:
First draw an oval.
Step 2:
Then draw two vertical lines below and connect them with arcs.
The third step:
In the middle, draw three more arcs, paying attention to the intervals, as the shape of the iron sheet.
Step 4:
Then draw an oval on top and draw two vertical lines as wooden strips.
Step 5:
Use short lines to draw the shape of the wooden bars inside the oval.
Step 6:
Use some short lines and arcs to represent the texture on the wood strips.
Step 7:
Finally, paint it with a nice color, and the barrel is ready.
