Dianne had put this one away for over a year, but finally finished. This is a great strategy that I've admired and wanted to try for a long time. Some of the theme fabric is used in the half square triangles, giving unity to the quilt. It works especially well with these blocks. Reference: Quilters Newsletter Magazine, October 2003, article by Sandy Turner. She states that she has tried several blocks for this technique, but "Birds in the Air" block works best for her.
