Myth #10: The flag must always be folded into a triangle for storage
Folding a flag into a triangle for storage, with only the blue union and stars visible, is part of tradition, said Hendricks, not a requirement of the Flag Code. Flags on a staff are properly stored in an entirely different manner that doesn't involve folding.
"Flags that are affixed to a staff are typically rolled around the staff and then a burlap case is placed over the flag and staff,” he said. “So, at that point, you can handle it like luggage. It's been properly stored."
