I am making half square triangles and want to turn them to make primative stars (essentially a 9 patch with a solid square in center and half square triangles around it- See pic). I can get the 9 patch to look like a star, but the problem is I don't have the ability to sew it to another block using a 1/4" seam with out loosing the points of the stars. What I am I doing wrong? I know I am missing something simple... Help!!!!
