If you bought it at your local quilt shop, you could ask if they put out a news letter. If they do, ask if you can put in a photo of the fabric and a request to buy some from anyone who may have bought it and has not yet used it.
Or you could ask, if they have a bulletin board, to post a notice and a swatch.
As well, you can ask at your local guild. Even if you are not a member, I am sure they would be happy to announce it at a meeting, I know mine would.
If you bought it online, then my suggestions will not help, except maybe asking at the guild meeting.
