Awww. You are not alone. No matter how perfect I cut, how perfect i try to make my seams, it seems I am always off. But you know what? Quilting is not about perfection. It is about making something, something you enjoy.
Made one this weekend and it was great until I put the last part on, then suddenly it seemed wrong. I started looking to figure out where it happened. It happened in the middle but was not noticeable until this last piece. So it is what it is, I'm not oging to take half the quilt apart to fix it.
