I have worked on quilts with great preparation planning only to find out that things went crazy somewhere. At that point I just wanted to eat nails. I am just finishing a really large scrap quilt which was made by sewing large and small odd shaped pieces together without a back support material. I did it in sections and then added one at a time with the idea of keeping it more or less square. But when I put it out on a bed it was going off in two corners very oddly. After battling with it for two nights I finally folded it in fourths in the middle and cut it square with the hope of starting another quilt with the left overs. Did I mention that I have two others that have been nicely packed away until I become more calm and have thought their challenges through?
