I have spoken to 10 people(plus me) about the meaning of the dicing on civilian bonnets.One(me)wear a diced bonnet.Why?Because I always have.The other 10 wear undiced bonnets.Why?Because they always have!Not very helpful.

We are all aware of some sort of pro/anti Crown/government meaning,but none of us can pin it down to anything specific.Most of us think it harks back to the Hanovarian time.Certainly nothing to do with the present Queen or her government.
