The address cards are available to download (pdf files) in both color and black & white. Printed on 8-1/2x11 paper. Make sure you set your printer setting to "Fit to Printable Area" to fit it all on one page.
Using scrapbook paper or cardstock (This is where those scrapbook pieces you save but never end up doing anything with them comes in handy!), cut out and punch holes into two pieces that are the same size as the phone/address cards. These will be your covers of your booklet.
