When I started my knitting class in 2005, we found out that Wal-Mart was going to get rid of their fabric and yarn. We got an 800# from the clerk and inundated them with calls complaining, then we started buying from them. They got the message and did not remove the fabric or yarn. They are even remodeling the department in February. The new Wal-Marts in the area do not have fabrics and yarns. But here we have convinced ours to keep those items.
Although I purchase most of my fabric at other places. Our Quilt Guild likes to take day/road trips to purchase fabrics for specific projects, but we still make purchases of substantial quantities at Wal-Mart to justify the department. One Wal-Mart is close to our extension office where we meet so it is a quick trip to make emergency purchases.
