Advent calendar 2

This is our other advent calendar tradition. We've had this for about 30 years now and it comes out faithfully every year... except for 2 years ago when I lost it.. For some reason known only to me, it is stored in the linen cupboard and not with the rest of the Christmas decorations and that year my memory failed me.
It is if course essential that the decorations are hung on carefully in the right order starting at the bottom left and ending with the star and the angel at the top... Not that I'm proscriptive or anything!
