Go to 3rd page and the link is there to the pattern, and also to the book with wedge rulers. I used sort of dark fabrics on the back so that it could go on the floor, and I quilted it more heavily so that it will take a lot of washing.
The rulers are a little expensive, but since I got paid for the quilt, it was OK. Not negative cash for me! And now I have the rulers to use for other projects. I'll be showing some more during the next couple of weeks...I have 2 more cut out already.
