We always had advent wreaths in our home growing up. They were never very elaborate and this illustration is the closest to the one I remember, most importantly the colors of the candles, with the lighter, pinker one being lit last as Christmas drew nearer. The candles were lit and it remained on our table when we had dinner, then hushed out after our meal. We did not begin our holiday decorating until Advent was over until my parents were older.
In recent years I've noticed ADVENT CALENDERS - with little windows and treats being sold in stores in my area, I believe imported from Germany.
