I am a member of the Prayer Quilt Ministry and we make quilts to be provided to those who are hurting or need prayers just like the recipients of the prayer shawls. We make our quilts lap sized, no wider than a width of fabric so we do not have to piece the backing. If the quilt is wider, we insert a large cross as the fill in to make the backing wider. I also was given a prayer shawl by one of my daughters and it is rectangular and lap sized.
