The Hirez PDF is sized for an 8.5” x 11” paper size. It is designed as a 2-sided document. Print one side and turn the page over to print the 2nd side. The text relates to each image. I recommend the image side be printed on the “best” printer setting. I recommend that you print on heavy cardstock for mailing purposes. These will trim to 4 cards 5.5” x 4.25” . They work with a postcard stamp or a letter stamp. Print as many as you like and share the PDF with your friends and family.
