I was a little confused by your calling it an “advent wreath”. It is quite common to light advent candles here in Sweden, counting down the number of weeks until the yule evening. Yule calendars are also fairly frequent, often with little gifts (chocolates, tea or whatever) for each day.
Then there are actual yule wreaths, which we often decorate our doors with, like this one:












Oh yeah, you could definitely find something like that in a Swedish home, although usually we have taller candles in the advent candelabra (so it becomes obvious that the earlier ones have been burning down for longer)
