This is how I do the math.
180squares/4(colors)= 45 squares per color.
I usually use 40" as width. So, 40"/5"= 8 squares.
Which means you can get 8 squares on a 5" strip (selvage to selvage).
Now you calculate how many strips you need to make 45.
45/8=5.6 round this up to 6. So 6 x 5"=30" which is 30/36= 0.83 yard
which you round up to 1 yard and you get a little extra for stash or insurance. See?
