Labels in Word are just tables with fixed cell dimensions. You can create
your own label template, either starting from scratch, or using a label that
is close to what you have and modify it. Note that some Avery labels that
have different numbers are actually identical so you might find one that
matchs the 6577.
Alternatively, the Avery website may have a template for that label.
