Aren't you eliminating a whole segment of the quilting world by not catering to the cost consious quilter. Aren't you also giving up a sizeable chunk of money to Walmart, Hancock, and Joann's who always have bargains for their customers who can't afford the top of the line fabrics.
I'm an avid quilter, I have fabric stashed in every nook and cranny of my home, but I don't buy the expensive fabrics. I firmly believe there are modest priced fabrics that will stand up to the "better" fabrics in all areas. Generic drugs are the identical to the name brand - only difference is the price of the name. I choose not to pay extra for a famous name stamped in the margin of the fabric.
