50 points, high score, please know! ! How to write the corner of POP poster font?

I am also an amateur pop lover. I usually write POP for company activities. Font corner is a difficult place, if no one teaches you by hand, it is not very clear. But I once read the blog of a fashion expert. He said that you can't use the concept of "writing" to make POP, but more "painting".

When I write a corner, I just rotate the pen evenly and then "draw" it. At first, there is always a corner missing. That's because the pen doesn't fit the paper completely and the wrist strength is not well mastered. It is good to practice more. This thing is nothing but practice makes perfect.
