Looking at the pattern of this quilt, it appears to be a block of 3x3 squares finished size). Using that as a starting point, I figured that using 9 inch blocks with 8 across and 9 down you could still have the same look but just one extra block high. With that , I was able to calculate that you will need 2 3/4 yds of various colors for the inside blocks, 2 5/8 yds of the blue and about 2 3/8 yds of black for boarder.
The outside boarder is also done in various colors the same as the inside blocks but you will want to do them a bit smaller. I figured around 6" maybe and they would take about 2 1/4 yds.
The finished size would be about 97" x 88"
Hope this helps
