I know how frustrated you are. I did a Jacob's ladder which should not be a hard quilt pattern to make. But I am sure I took that whole queen size quilt apart more then once. I like to chain piece so I would get started and sew a whole bunch together and then realize I had sewn them on the wrong side. So frustrating.
I think the thing to do is pin them all together than sew them. I hardly ever pin anything and that is why I got them all sewed together wrong. All it takes is to pick up the pieces and turn them when you put them in the machine and they are all wrong.
Have a rest maybe it will go better later.
