That is an excellent tip, for I have been doing that for years. It is amazing that so many have never heard of matching the points and sewing them at each point, making sure they all match before sewing the final seam. I also will turn my fabric upside right or upside down where ever the seam needs to be eased together and my points don't change. I myself feel that the end product is worth this little extra step. One does not hurry.
