Don't shoot me, but if you feel that you have to rip out all the seams-isn't that handwork? LOl I know, I'm sorry. I couldn't resist. And I haven 't read all the posts so if someone else already said it, please forgive me. But if you piece the whole thing with the same seam allowance, won't it still come together correctly? If there are points-maybe not. But unless someone is perfect, we have all been there.
