Finishing drywall comes in many different skill levels. It is fairly easy to hang a few boards and tape coat them. That is 101. Having had a water leak damage the ceiling, or someone step through in the attic or just a random hole in the wall requires experience and what I call a ” third eye”. You will find, anyone (few & far between) who can repair a hole like it was never there, is artistically inclined one way or another. The experience paired with the tools, materials and the third eye will achieve the intended goal.
