This is "Diamonds Are Forever" by Roger aka/Freedman. The link I had to this pattern no longer works. Thread is Lizabeth Country Turquoise Med #661 and ecru, size 20. I started this about 2 years ago and when you look closer, you can tell where I stopped as my tension is tighter than it was 2 years ago. This finishes to 10.5" across and is the largest doily I've made to date.
