Since,apparently you have a minhag to braid challah, and to use three braids, would you share the reason for your minhag.
The reason for my “minhag” is that three is easiest for me.
You seem to be offended by the reason offered by RebRy, perhaps you can afford a more profound reason, and not resort to the mundane.
Who said I was offended? I was merely pointing out that not everyone uses six braids.
