red,white&blue

I put the pieces for this quilt this way and what they needed to do is have the blue squares follow in a diagonal line while the red squares follow in a diagonal line the other direction.  I had sewn 32 red blocks and 32 blue blocks together this way, which is wrong.  I thought of leaving it but decided I really wanted it to look the way it was supposed to.  So I unsewed 64 blocks, just the long center seam.

As you can see on the center picture, this is how the blocks are supposed to go together.
