Apple phones can directly use the memo function that comes with the iphone. After opening the memo, we can adjust the color and brush, and then we can start drawing the Christmas tree.

1. First, we open the memo that comes with the iphone, select the color in the lower right corner and the brush in the lower left column.

2. Draw three shell-shaped patterns that decrease from bottom to top, and then draw a five-pointed star at the top.

3. Then draw a rectangular pattern below as the trunk.

There is a line around the Christmas tree, and many balls are hung on the line.

5. Then paint the trunk brown with a brush. The stars are yellow and many balls are colored. In this way, the stick figure of the Christmas tree is completed.
