S. Flag etiquette wrong. It’really quite simple. Please, have a quick read and correct your mistake. Patches are cheap and so is the thread.

* When placing an American flag patch on a sleeve, the key is to ensure the star field (union) always faces forward, as if the flag is flying in the breeze as the wearer moves. This means on the right sleeve, the flag is reversed so the union is on the right side (observer's left). On the left sleeve, the union is on the left side, as it would be on a standard flag.

Here's a breakdown:
Right Sleeve: The flag is reversed (stars on the right) to create the effect of the flag flying forward as the wearer moves.
Left Sleeve: The flag is in its standard orientation (stars on the left).

General Guidelines:

Military:
Military personnel typically wear the flag on the right sleeve, reversed, so the stars are forward.

Civilians:
Civilians can choose either sleeve, but the forward-facing rule (stars forward) should still be followed.

Respect:
The flag patch should be placed on clothing or gear in a respectful manner, avoiding placement on the bottom of a bag or on items that could be easily soiled, according to www.thestudio.com

Placement with other patches:
If other patches are present, the flag patch should generally be placed above them, says www.theflagshirt.com
