How about some pictures? Honestly the binding is usually the thing I dislike the least - I can always notice a crooked seam, mismatched corners, over abundant stippling, but the binding always looks so nice and clean.
Maybe your last cut of your quilt is not clean so there is no hope for the binding. Some folks must square their quilts up nicely before doing that last cut before binding.
What is it about your binding that you don't like?
