I wanted to make sure I wrote these down (before I forgot!)
Julie over at Trinity Acres has a posting up for the Loveliness of Lent. She has created some great Lenten calendars which would be a great resource for anyone with children!
Illuminated Ink has a Lenten coloring contest and some great resources, including a Stations of the Cross kit and this 3-D Passion Play kit that my kids would loooooove (as you may recall, we color and draw for HOURS over here!)
The Lenten blogsite, These 40 Days, is a great place to check out what other families are doing to live out this season.
Just some more options to throw your way!
