The sheetrock tape worsens the problem and requires way way more paint. I throw out the entire project thinking there’s no way I can do this.
After returning from the dumpster, I begin cleaning my apartment and find…
An idea hits me. I can use the black plastic to cover the lines, paint the whole thing white and the shadows should disappear. It seems to me this line of thinking is logical and sound.
I go back out to the dumpster, removes all the parts of my project, and return to my apartment.
