I do mine in stages and I just finished 12 blocks. I sew two of the diamonds together with the square for the corner, set them aside and do the next set. I do this until I have them all done, then I press and add the triangle then put two of the sections together and add the second triangle. Then I lay that half block aside and make the rest of the sections into half blocks. Finally I sew all the half blocks together and I'm done. They don't always turn out perfectly but close.
