3. Select "Filter > Render > Layered Clouds", and your scene will already be able to see cloud-like graphics mixed with black and white.

9. Choose Filter > Distort > Displace, using the default parameters. Then select the board.psd file you just saved. The effect is as follows:

10. If you are not satisfied with the window above, you can use other brushes to adjust it until you are satisfied. We can also add other adjustments such as color, other filters, etc.
In actual operation, not only the border can be processed in this way, but also any other shape can be processed in this way, and the effect can be used as you like.
