Here is something we could try but don't know if there are enough sewers/quilters to do it, or if it would even make an impact on Walmart.
on a certain day we all mail an empty envelope to the walmart head office and on the back of it write that this envelope represents a sewing customer that wants fabric back/stay at our local walmart. if it doesn't we won't shop there anymore.
or we could all call the home office on a certain day and that would crash their phone lines & get their attention (if enough called). we could all email on a certain day-again it would tie up their email dept & get their attention. I think that would work the best (save a stamp, be more convienent, etc).
but no matter what we chose to do, there has to be tons of us or I doubt they would pay any attention.
