here is another thought. Three pins....first straight down thru both points and while keeping that pin perfectly straight, take a small bite from another pin on either side of that one, then remove center one.....go very slowly to first pin, remove it, and sew to point, but not right on that X, just a thread over into the seam allowance, then slowly move away to the other pin, remove and finish sewing. The reason you sew just a thread away from the junction is when you turn to right side the actual point is finished.......Takes time, but its worth it......and after awhile it becomes second nature.....
