Mourning stationery

We have discovered more than a dozen letters written on mourning stationery. According to Emily Posts's Etiquette: The Blue Book of Social Usage (1927):

Persons who are in mourning use black-eduged visiting cards, letter paper
and envelopes.  The depth of black corresponds with the depth of mourning
and the closeness of relation to the one who has gone, the width decreasing
as one's mourning lightens.  The width of black to use is a matter of
personal taste and feeling.  A very heavy border (from 3/8 to 1/2 of an
inch) announces the deeptest retirement, but these heavy borders are now
rarely used, the tendency in recent years being to avoid anything so
extreme; 1/4 of an inch is considered sufficient for deepest mourning, or
even 3/16, while 1/16 and 1/32 of an inch are suitable widths for second
mourning.

Wow! Such attention to detail. I wonder if we could follow such strict specifications for mourning e-mail.
