I've read that 3 is the traditional or customary number of Merit Badges on each row.
However, are there any rules on how to display them on the sash. i.e
* Are 2 MB on each row ok?
* How about 3 on one row, 2 on the next, 3 on the next, etc.
I can't find any official rules on this, and my son put 2 MB across on his sash. The Scoutmaster told him he wasn't sure if that was ok or not because he has only seen 3 across. I'm looking for something definitive I can point to for my son if he needs to change them or to help the Scoutmaster have the support he needs if others complain to him.TIA
