Cardstock is a year's worth of cards in a box. 40 cards (printed on 100% recycled paper) provide for a year's worth of birthdays, holidays, thank yous, get wells, anniversaries and more. A bargain at $60, they are available from Set Editions.
While shopping pick up a very handy pack of Alison Riley's "Stop Talking" cards. These classic cards started the Set Editions company in 2004 and always come in handy.
