The easiest way I have found to make those star points is to use the method of sewing two squares together on all sides with right sides together, 1/4 in. seam all around. Cut on diagonal to make 4 half square triangles (hst). then just turn those hst around a square of the same material and get all those points without cutting off anything. There is a stream on this site that give you the measurement for the squares in order to get the correct size hst. Missouri quilt also has a youtube demo to do the hst that way.
