Oh,hon, I know what you are going through. It's there somewhere, just that you can't see it. Keep looking. Also, have you tried praying to St. Anthony, the patron saint of lost objects? I am an agnostic, but I do swear by St. Anthony.
St. Anthony, St. Anthony, come around, come around. Something is lost and can't be found. Remind him you are doing this project for someone else and he'll help you. Especially if you go out and buy more green fabric.
