Every year I find myself looking for Advent ideas. We like having a family gathering time each evening during Advent, and I often provide some kind of related activities for our Squirrelings to do during the days as well. Although I'd like to try Ann Voskamp's new Glorious Coming study, we've done the Jesse Tree-type Old Testament symbols several times over the past few years; we've also done the Names of Jesus and so on. One year we did a four-week look at the Gospels: one week each for Matthew, Mark, Luke and John. (Maybe next year we'll get a copy of Ann's book.)
Anyway, a church bulletin insert last weekend pointed me to the Mennonite Central Committee's printable Advent Calendar (click on the Advent calendar link there). [UPDATE September 2007: last year's calendar is gone, and this year's isn't posted yet. Sorry!] It's a two-page PDF document with brief notes for each day in Advent. Several of the days have notes about MCC projects going on in different countries. It's too sparse for our family to use just as it is, but I'm working on some ways to expand the ideas. When I get my plans together, I'll post them for anyone else who can use them. [Update: our plan for Advent is here.]
Here's a link to last year's post about our family's Advent traditions.
