Did the center star line up properly before you set in the side triangles and corners? I would begin there. If not, you probably didn't have consistent 1/4" seams. If so, then the rest of the star will line up and you will have to redo the side triangles and corners. The previous posters are correct - it is easier to make them bigger and trim. It will take some re-working but the colors are beautiful and it will be stunning even if it's not perfect. I'll take it if you really don't want it. lol
