Word's Mailings tab allows you to create cards from a list of member data. The data can be in an Excel worksheet or a Word table or many other formats. Choose Mailings>Start Mail Merge>Labels, then click on the Options button to select a card size. Word will create a table that corresponds with the arrangement of cards at your chosen size. You can format each cell with a logo or other graphics, then use the Select Recipients command to add data fields from your data source.
