Material preparation: a piece of paper, pencil and colored lead.

Operating steps:

1. First, draw a rectangular box of red envelopes on the paper.

2. Add a small box to the drawn frame, and write the word "Spring" in the small box.

3. Draw RMB at the top of the drawn frame. It is necessary to distinguish the lines of money from the lines of red envelope ears to make it look more three-dimensional. You can determine the amount contained in the final red envelope according to the amount you want to withdraw.

4. After the above steps, draw a sealed red envelope, or draw a big box with a small box in the middle and write the word "Spring". Now the basic frame diagram has been completed.

5. After completing the above steps, the big red envelope is basically completed, and the last step is coloring, which is a very crucial step. If the colors don't match, the whole work may be wasted.

The cover of the red envelope should be red, but the small box on the cover of the red envelope should be orange, so as to distinguish it. The word "spring" can be painted black and bold, and the amount of money exposed in the red envelope depends on the amount drawn. For example, 100 should be painted red, but lighter than the cover of the red envelope. This is the whole process of drawing big red envelopes.
