Fabric manufacturers design, sell and abandon their lines faster than bra models or silverware patterns could ever think of doing!! Has always been thus, likely always will be, as the market is consumer demand driven. Sure Hancocks of Paducah sells lots of fabric, but they are surely not the major retailer the manufacturers are catering to.
so sorry you've lost out on this BOM, it must have been wonderful, but any fabric you saw new 4-6 months ago is probably well out of production by now. On to bigger and better things is the way of it.
