Boy Scouts of America merit badges should be placed on the Scout sash with a spacing of half an inch between the top edge of the sash and the top edge of the badge. Scouts can place badges on the front or back of the sash.
Merit badges should be sewn in even rows between the two hemmed edges of the sash. Three badges fit side by side with this placement on a wide sash; two badges fit on a narrow sash. Scouts must wear the sash over the right shoulder with the BSA uniform. Only one merit badge sash should be worn at a time, and the sash should only be worn at formal occasions.
