1 Advent Build a Scene Sticker Calendar. This is a beautiful and symbolic calendar to celebrate Advent and the true meaning of Christmas. Instead of aspiring for a small chocolate, children can day by day place a sticker on the calendar to build up the Nativity scene. Each day they recreate the Nativity and have a lovely finished scene to treasure.Each pack has a 3D card background with a sheet of 25 stickers. The card background has two sides - one with numbered places to stick each sticker: the other side is open ended to allow older children the chance to create their own scene. Calendar measures 28cm by 21cm.
