def going to have to take your star sections apart......looks like issues start in very center - you should have 8 diamonds in center of your center color and it looks like you've lost part of that (not sure if it's in sewing or where), but that is throwing you off all the way out. I agree with cjsews about pinning each seam on your star sections and then love the idea of applique to one large piece of fabric (wish I'd thought of that with mine, lol). Good luck.....it's too beautiful to give up on!!!!
