My former church makes them and gives them away. They use 6.5" squares and piece the quilts in 6 x 9 rows. The quilts are sewn up and a backing added. They are then turned envelope style. You may or may not sew around the outside perimeter. The ties of yarn are then put at each intersection and a prayer said over each knot. We did not sign our names but put a label on the back saying who the quilt was from and the date. Hope this helps. (We work in groups: some cut, one or two arrange the new quilts in a pleasing design, and others sew, and others iron.)
