This one's just a tad over 44 x 44 inches square. I picked out 8 of the blocks that had a slightly maverick interpretation of the heartstrings guidelines... you'll see some that have no red stripe at all, no centered red stripe, or too small or too large of a red or blue stripe. In this layout, with the red not forming a lattice, the variations don't matter at all.
I didn't chop one up to make the cornerstones, but instead made 4 new little blocks the size of my inner navy border that 'floats' the star.
Now that I look at it, if I were to do it again, I'd rotate those cornerstones so that the strips go diagonally the other way, but I'm certainly not going to rip them out and rotate them now... :)
