I followed the link for that pin link you gave. That took me to Sew Kind of Wonderful blog spot. These quilts take their special Quick Curve ruler to make. If you follow the link and scroll toward the bottom of the page you will see this quilt. Good luck. I would advise you to get the ruler. I have it and it makes these curvy quilts easy to do.
