Oh and one last thing, when you sew remember the eye sees up the center line less side to side, so pin to make sure that the inside works, the outside is okay to be off a bit.
That one there all the way on the bottom? Remember it's not the finished project that one looks funny because it hasn't been sewed in yet. If you don't believe me, fold it down at the edge 1/4" and look again, it's fine. :D Triangles look funny at the edges it's nothing to worry over.
