I looked at your dilemma and thought, I'll just draw this in EQ7. Well, it has decided that it doesn't like your measurements at all. lol Maybe it's just me??? : All my numbers are finished lengths and have to have extra added for quilting shrinkage! I long arm my quilts and I leave at least 3 inches on each side for this movement. Even, if you quilt yourself, you need a little bit extra.

You appear to have divided the quilt in half, from top to bottom, and then side to side. That makes the calculations easier.

For the length, you appear to have drawn out the sections by dividing by 8. Meaning, that 3/8 of your quilt is the top part, then you will have the center where you change your colors which is 2/8 and then the bottom which is the other 3/8. If you add these up, you come up to 8/8--- 1 whole measurement. I upsized your length to 72 inches because you need some extra and 72 is divided by 8 = 9 inches x 2 parts for those middle inserts. At first I thought you wanted squares for the middle, but then I realized they are slightly rectangular. They look like the center blocks would finish at 9 x 10 or even 11.

Think very simply from here on out. My suggested sizes with adding just a bit to get some even divisions:

1. You have two rectangles at the top of the purple and the blue. You have the same on the bottom but in green and pink.
Top & bottom rectangles would be (52 divided by 2 = 26) by (72 divided by 8 = 9 times 3 = 27)
2. Then you have two parts that go from one side to the other with 4 parts to each. The center two parts could be 9 inches wide by 10 inches height which is what I will base my calculation on. That means 52 - 20 will be 32 left, which gives you a 16 x 9 inch strip on each side of your center inserts.

Now, let's check my calculations.
1. Width - Top & bottom 26 + 26 = 52
2. Width of Center - 16 + 10 + 10 + 16 = 5
Yay!!! That one worked out.

Now for the length verification:
Top & Bottom rectangles 27 + 27 = 54
Center 4 blocks 2 times 9 = 18
18 + 54= 72
Now add a few more inches to my measurements for your shrinkage. And thanks for making my brain work a little today. Sorry for the wiggly lines. I don't have a real mouse and my finger doesn't draw straight lines.

Edited to add: working with EQ has taught me that I have to have a sewable block. So every time I look at a problem, I decided how I am going to sew, and the rest seems to just fall into place and make sense.
