Thanks for the great idea. I am going to use blank index cards because I haven't got time/talent to make the cross with the other materials, but I like the idea. I'm not sure if I'll use the 3X5 or larger size. Anyway I might just attach these by strong tape to a large wall or glue them to larger posterboards. I'll let the kids do the artwork with a variety of mediums (paint, 3d -whatever works!) God Bless, Rani O'Donohue
