Per EQ7.... With 8 inch blocks - 12 x 13 is a finished size of 98 x 106.
The fabric requirements are
background - 13 1/8 yd
Light blue - 4 5/8 yd
Dk blue - 4 1/2 yd
No borders were considered in this, but there is an allowance for a 1" binding.
I then added changed the layout to 10 x 11 blocks. A first 2" border of background. Then a 4 inch border of light blue, then a 6 inch border of the dark blue. Final size with a 1 inch binding is 103.5 x 111.5.
Background 9 1/2 yards
Light blue 4 3/8 yards
Dark Blue 5 3/8 yards
NOTE: I have never actually bought fabric based on EQ, but knowing all the details in the program, I would bet these numbers are fairly correct.
Edited to add: If you want to change any of the numbers, let me know and I will edit the file. Also, I found that if you make the tiny outside edges of each block a different color, it added a pretty variation.
