Christmas Labels

Hi I would like to be able to use mail merge , to import my address book into sheets of labels, but when I go to mail merge and follow the directions it doesn’t have a "labels " option, only letter and something else.

No idea what format / based on what software your address book is. Let’s suppose it is a spreadsheet table registered as a database or another kind of database table accessible by LibO.
Did you read (e.g.):
https://help.libreoffice.org/Common/Printing_Address_Labels
or (older but more detailed:
https://wiki.openoffice.org/wiki/Documentation/OOo3_User_Guides/Writer_Guide/Print_labels_from_db
and:
How do I create labels from a spreadsheet? ?
