Wonderful quilt Betty! So based on your description of how you did this you basically did the Deb Tucker method without her ruler. I have made quilts with loads of FG without the special ruler. I was pleased with the result. But I picked up this ruler last year and have to admit, it definitely is a great specialty ruler, well worth the investment. So add me to the list of supporter for the Wing Clipper.
Also I don't care what color the "sky" units are, I always press towards them.
