The Jesus Tree is such a wonderful way to do a Lenten Bible Study with your children. We really enjoyed it last year!
I spoke with the owner of Scripture Trees (a very sweet Catholic mother) and they are still selling their kits, though their inventory is getting low and they won’t be making any more until next year. The price is the same as when I purchased ours a couple years ago, just $10 plus shipping. Scripture Trees is a small family business and she said they don’t have a website (yet) so you can either email them at scripturetrees[at]usfamily[dot]net, or call 651-426-2174 to place an order. (You will probably need to mail a check before shipment, so hurry. Lent begins February 25th!)
Also, as I made our ornaments last year, I posted pictures of them, as well as the bible readings (we used the New Catholic Picture Bible (NCPB) by Father Lovasik) and an activity and/or coloring page for each day. For convenience, I just added the links to those posts to my sidebar, and I’ll leave them up until Easter.
