I am in my LQS at least once a week. I have noticed fabric quality has deteriorated for most fabrics. Manufacturers are cutting costs any way they can.
If using a Long Arm I caution all to reconsider using sheets for backs of quilts. The high thread count is wonderful to sleep on but the needle cannot slide through the thread count. Instead the needle "breaks" the threads. Over time this may create holes in your back.
Happy Quilting!
