I am about to make a quilt that is 86" x 86" using 5" squares. Because I am using a design that will cause me to lose in seam allowance more than a quarter inch all round, I am basing my requirements on a 4" square. I have calculated that I will need 12 packs of 42 squares each to be in the safe side.
Could some much more experienced quilter tell me if that sounds reasonable please?
