Contrast squares: You will need to cut 2.5" strips along the 21" side. You will get 8 strips (8x2.5=20), then subcut 2.5" on each strip. You will end up with 7 from each strip for a total of 56 2.5" squares from each fat quarter.
Combine the 6.5" and 2.5" blocks for the plus sign. If you add those it is 9", so cut along the 21" side the 18" width. You will get 8 18" strips that you will then subcut into the 6.5 and 2.5" pieces. So each fat quarter will yield 8 plus signs.
If you are using yardage (not fat quarters for the snowballs, you can get 16 2.5" squares out of WOF (assuming 42" wide). If you need a total of 720 total (90 blocks using 8 each) then you will need 45 strips at 2.5 each. That is 3.125 yards or 3.-1/8 yards. I'd get 3-1/4 or so just for squaring up.
Okay, someone else check my math!!
