Before we start drawing the jerrycan, we need to talk about it a bit, because it's quite an interesting thing. The fact is that it has many cool design solutions.
First of all, it is called a jerrycan because of the Germans who actually designed it.
Then, the jerrycan has three handles, so two people can carry it using the outer handles, or one person can use the middle handle, depending on how heavy it is.
Next, it has a special air pocket located above the neck, so if you fill it to the brim and then drop it in water, it will float.
For rigidity, it has special recesses on the side walls. These also help the canister not to rupture during heating and cooling.
The neck is also quite cleverly designed. First, it has a built-in cap. Second, you can't see it in the picture, but there's a special tube in the neck. One end sticks out from the neck, and the other goes into the air pocket. Thanks to this, when you start pouring something from the jerrycan, it doesn't gurgle, and the liquid flows in a steady stream.
Now let's start drawing. The body of the jerrycan has an aspect ratio of approximately 4 to 6. In the upper left corner, we'll have a bulge for the air pocket.
After we've dealt with the shape, we need to add handles, the neck, and the relief on the side wall. We can also add colors.
