Actually if you will take a seam just a thread or two smaller as you get to the point where they will all come together it helps. Also when sewing it together, do one side and then the other, then when you put the center seam together sew from the middle to the outside in one direction and then do it the other way from the center out. Then turn it over and spin the center seam all in the same direction. If you aren't quite accurate with the seam and it isn't sewn to the point, this will not show. I just did this with the mariners compass and had no mountain in the middle. Some wise lady, who is no longer with us, Phyllis, taught me this.
