Applying the last instrument, insert a figure of white color in our picture.
Merge down now all the layers containing this
in a group.
Copy this new made group 4 times and apply Free Transform selection to minimize it or increase it if it’s necessary.
Turn it around now on 180 degrees horizontally.
If it’s necessary, you may apply this instrument to make the appropriate corrections. Place everything out like it is shown next picture.
The final result!
