For a long time I have been intrigued by the Jesse Tree tradition that a lot of families and churches participate in during Advent. It seems like a neat way not only to focus on Christ in anticipation of Christmas, but to also remember what His birth means in the context of the rest of the Biblical story.
If you are interested in possibly starting this tradition in your family, you might take a look at these blog posts from families who have done the Jesse Tree in their homes. I think it's really interesting to see how each family has tailored the basic idea to fit their family's personality.
Also, at the end of this post you will find a collection of resources (printables, devotions, etc) for help in making your own Jesse tree.
A list of Scripture readings and description of the tradition from CRI
