I am sewing triangles in a line and then the line will be sewn to a sashing. The problem comes in that there doesn't seem to be a 1/4" being left at the top and bottom when I sew the triangles together so that the points come out right when sewn to the sashing. The points are too close to the edge and when it is sewn to the sashing, I am going to lose the points.
Clear as mud?
Is there a trick to sewing triangles together this way so that you get that 1/4" to seam with?
