Of course, there's the time you sew the seams together wrong, rip and sew them wrong again, only to find out if you had turned the project around the seam would have been right. Or you could get the backing just right, set it aside. Then you need a piece of the left over backing fabric for another project. As you are ripping of the "hunk" you need, you realize you are ripping you correctly sized backing. Done it all :wink:
