No quilt deserves to be trashed! At the very least, store it with your UFOs in the back of the closet for a while. I'm sure you will get some wonderful suggestions on how to fix it here. It's 2:30 AM here right now, but in a few hours, folks will wake up and there will be tons of help going your way. For now, take a deep breath and have a cup of coffee. BTW, it really is a beautiful quilt.
