Today I'm doing a re-run of sorts; this time of year the most frequent Google search that lands people at my blog is "Jesse Tree". I wrote about this Christmas tradition at length last year--if you missed it, below are links to all the posts.
(And no, I don't think it's too late to jump on this bandwagon this season. You might have to scramble a bit, but it would be worth it. At the very least, you could begin working on your Jesse Tree for next year, while all the Christmas ornaments are on sale! I was at the mother ship yesterday and bought a three-foot Christmas tree for $6. It would be perfect for a Jesse Tree.)
Also, see this post at Bloggy Giveaways on the subject.
