I may be a fabric snob but Walmart fabric is out of the question FOR ME and JoAnn's isn't much better. For the amount of time and money spent and hoping that what I create will last a long time, I choose a true quilt store. That being said, I usually will make the treak to Lancaster PA where most of the fabric there is in the $6 range, true QS quality fabric. I'm headed out tomorrow to Berkholders, 25% off and their clearence is down to 1.75 and 3.00, for quality fabric.
Just my 2 cents.
