Today's Solemnity of the Annunciation of the Lord (that's the real name) is a great day to promote the prayer of the Angelus. To make this easier for you, I have prepared a kind of holy card that you can download and print with business card paper (I formatted it to Avery 5371, but you can fiddle with it to see if it will work with other pre-cut cards). You may have to work a bit to back them up correctly; it's a two-sided card (so download both front and back).

Keep a few for yourself in handy spots to help you remember to pray the Angelus morning, noon and evening--or on your commute to work, at lunch and on the commute home.
