Direct answer: In the United States, when a flag is placed over a casket for a funeral, it is draped with the flag’s blue field (the canton) over the left shoulder of the deceased, and the flag should rest on the head end of the casket for a closed casket. The flag is not to touch the ground, and it is usually removed and folded into a triangle (the 13-fold flag) after the service, then presented to the next of kin or stored appropriately. For open (half or full couch) caskets, the flag placement varies slightly to ensure the blue field is positioned toward the head or upper portion of the casket, typically with the flag arranged so that the field is over the deceased’s left side, and folded properly at the conclusion of the ceremony. In cremation or other ceremonial contexts, flag handling follows similar folding and presentation practices. If you need a step-by-step guide tailored to a specific casket style (closed, half-couch open, full-couch open) or to align with a particular military or organizational protocol, I can provide a detailed checklist. Please note that exact practices can vary by branch, organization, or funeral director, so consulting the funeral director or the relevant authority for the service you’re coordinating is recommended.
