An Advent calendar is a special calendar used to countdown the days in Advent in anticipation of Christmas. The first Advent calendar was used in the 19th and 20th centuries by German Lutherans and has since spread to other denominations. New to the Stampin’ Up!

Each day’s treat or surprise is contained within a completely customizable 3 x 4″ envelope. Oh, what fun! Bring a classic, cozy Christmas feeling to your home this season!
