More options and custom labels 

Address labels are the most popular kind of label, but you can also find special printer paper for making things like business cards. On the Mailings tab,click Start Mail Merge - Labels. You can look through the list of vendors and product numbers and find templates for all kinds of labels.

Save your label file for next time

Then, if you want to change which people or items you include in the merge, click Edit Recipient List to sort, filter, and select them.
