Material preparation: A piece of A4 paper, a pen and a colored pen.

Operating steps:

1, draw the castle walls and windows first, and then draw the entrance.

2. Draw three platforms and a pillar on the castle.

3. Draw two top pillars on the side.

4. Paint the windows and the tops of the platforms blue, and paint the posts pink.

It would be nice to paint the columns and castles purple.
