All these beautiful magic formulas and no one has the same out come. I definitely will not throw stones because 9th grade algebra ate my sack lunch.
The link for the pic isn't working so I don't know if this would work but can you not find your smallest block and trim the others to match like someone else here suggested? Can you not just decide I want the quilt this size, divide by # of block on a horizontal row and on a vertical row?
