Many years ago I heard Marianne Fons say "I have made quilts that have perfect parts but I have never made a perfect quilt ". This from someone considered to be a master quilter. I have seen quilts in magazines and they have points that don't match, I think striving for perfection puts too much pressure on you and takes the joy of creativity away! I say do the best you can to achieve the result you want and move on to the next one.
