DO add a brief message, in your
own handwriting, to a printed impersonal card,
adding warmth to it.
DO personally sign even
name-printed greeting cards. Else it makes your
card look cold and is a sign of bad manners. The
name is printed on the card for clarity and it
is courteous to sign the card yourself.
DO sign in joint names, if your
card is printed jointly in the name of a couple.
DO acknowledge greetings received
thanking the sender for remembering the occasion
and for sending the card.
