I love the colors, especially the red. And yours points/seams come together so well.
Would I be correct that you did a strip set of white-red-white, and one of blue-white-green, attached those, and cut? I've done a similar pattern, but did a center square, add 4, strips of color 2, add 4 strips of color 3, and repeat for each block. Your way seems substantially simpler!
