I have the patttern, so I checked it out for you. :)
For a Queen Size, finished size, 93" x 102". Needs 30 fat quarters of your choice., 2-7/8 yd. for border and binding and 8-1/2 yds. for the backing.
For the King Size, finished size 120" x 120" you need 48 fat quarters of your choice, 3-1/2 yds. for backing and binding and 10-5/8 yds. for backing.
Hope this helps you.
