If you hear that your local W-M is going to close its fabric department, call the corporate headquarters and request that they keep their fabric at that specific store. The clerks in the fabric department can tell you where to call and give you the store number.
When our W-M was going to remove the fabric department, we asked all of the members of the local guilds to call. We also asked parents of students at the local schools to call, since most of the students get their fabric at W-M for their sewing projects.
Due to the number of call they received, they decided to keep their fabric department. That was about 3 years ago.
