As I stated in other posts, it helps to baste those point and side seam areas with a longer stitch length. If any points or seams are off, it is much easier to take out those stitches and is less stress on the fabric when using a length of 3.5 or so. When the seams and points match up to your liking, go back and change the stitch to your shorter desired length and sew the longer seams. In my experience sewing the points and side seams first, I find I can finish more quilts- faster and with less frustration because I am not taking out seams and re-doing blocks when the measurements are off or I am not happy with those wonky points. Along with measuring finished sections and blocks while sewing, it is one of the best tips I learned when I started quilting so long ago.
