Want to encourage you to figure out how to fix it - the star is BEAUTIFUL!!! Also want to give a thumbs up for trying this - it skeers me!
I wonder what would happen if after checking the star - making sure that it is all lined up like it should be, then put the star on your flannel board - and add the brown pieces cut individually to make sure that everything stays smooth. It is definitely fudging it, but you might fool the eye.
