I couldn't wait to post this stained glass liturgical pattern. This is a marvelous example of the creativity of antiquity. It is a "christogram" or logo which was used in the early church. The two greek characters, "chi" and "rho" are the first two letters of the name "Christ". This pattern is free if you make it for your sunday school, pastor's office or church school. Provide a photo of the finished product, hanging in its final location, and provide you either with another pattern, or refund your $. My gift.
