You can try posting an ad on Missingfabrics.com
There are people like me and not just shop owners with large stashes of all sorts of things, you just never know. If you do post an ad, please make sure to check your email account and update your posting. I probably have exactly what people want 3-4 times a year and never hear back and the ads aren't taken down and typically I offer my fabric for free (wouldn't in your case, but that's another amount of yardage!).
There are other lines out there, I had out a piece of chocolate with sort of turquoise jacks/star shapes on it out yesterday. Unfortunately I moved things around and so wasn't able to find it yet (but I'll keep looking). That luscious chocolate/turquoise combo was around for maybe 5 years.
