Signing X-mas cards

Miscellaneous and Personal Stuff I Must Share

Anyone here use their full name?

I have looked at the cards that I have got so far this year, and no one friend or family uses their full name.

I like my name. First middle initial and last.
This is how I will be signing my cards this year.

Is this a breech of etiquette or what

I usually sign my full name on mailed Christmas cards. Not that it matters, as my signature is totally illegible and looks nothing like my actual name.
