I have a question about a planned display of 24 national flags on a wall (birth countries of students and staff at a Jr. High School). Is it a definite violation of protocol to display the 3'x5' flags on a 15' high wall in rows? I realize that the flags in the top row would be "higher" than the other flags. The U.S. flag would be uppermost viewer's left. Also, is the alphabetical order of other countries mandatory? We may very well be adding new flags and it would be a lot more work to "insert" a flag rather than add it to the "end" of the display. Thanks in advance for any advice.
