This is how I do it but use a Frixon pen to mark where the pin in the point is as a sewing guide as it can be awkward to keep that pin in place while you are sewing. By marking the point you can have a line of stitching that has several points along the way. I'm a point and corner seam match fanatic and this works for me. I use the Frixon pen because the mark comes out easily when I iron or wash but any washable marking pen will work.
