"In OpenOffice, click the File menu and select New -> Labels.
A new window titled Labels should appear. Select the Brand then
select the specific type of label. Most labels made by other
manufacturers have an equivalent Avery type, so look down the list
to find one that matches your labels. In my case, I chose "Avery
A4" for the brand and "L7159 Address" for the type (3 columns x 8
rows on an A4 sheet)."
