Return address labels

[Frustrated]

I'm new at using mail merge in Word. Is it possible to create mailing labels
where I can have a company logo & address information and merge in different
customer information onto each label? (Printing everything to a blank
label.) I haven't been able to figure this out. Everytime I go thru the
merge process, it ruins any formatting I've done.

I tried downloading Avery label templates, but short of manually typing the
changes on each label, I can't figure out how to use them with mail merge.

Thanks for your help.
