You're speaking my language! And I do not like to redo things at all, but that's just me. I've handled it by adding tucks (the border was really wavy and the border fabric was a busier fabric - I couldn't even find the tucks after it was quilted); doing a tighter piano key type quilting in the wavy areas; and having the fuller part against the presser foot when I attached the binding, working the fuller part in by slightly stretching the binding. After my quilts are washed they are pretty flat.
