ChristyH! I read that you have another green that matches but does not have the gold on it! Do you FMQ? If you do FMQ, I would try using a gold thread (I'm sure there is a gold thread for quilting out there) and FMQ a similar design onto the green fabric. You may not need much but just enough to help it match. I wish you luck. These types of things happen all the time and we just have to take a deep breath and figure out how we may make it work.
