How to draw colorful national patterns?

I suggest taking the following steps:

Preparation tools: paper, pencil, marker, eraser.

Draw a circle as the outline of the snack.

Within the circle, draw another smaller upper circle as the top of the dessert.

Draw a wavy line as the edge of the snack.

At the top of the dessert, draw a semicircle as the lid of the dessert.

Draw some dots on the lid as decoration.

Connect the bottom and top of snacks with curves to form an arc.

Draw a few small circles as the internal structure of snacks.

Connect the two sides of the arc with a curve to form the side of the snack.

Draw a wavy line under the edge as the shadow of the snack.

Draw a projection of snacks.

Color snacks with colored pencils or watercolors.
