We try to enjoy Advent as a full season but only do the days in December. Also in December, we hit some holidays/highlights like St. Nicholas Day, St. Lucia Day and Winter Solstice.
In the past, we've used calendars with opening paper doors, and we used an Advent spiral with a candle too.
We have "baggies" with the numbers on them, but last year those even felt superfluous. We have a little Elf with pockets named Nick the Nisse so I think we'll just stick with him for now.
