Also, more frequently these days, I have noticed the fabric width has gone down from 44-45 inches down to 42-43 inches, so that may have an effect on the 22-inch width also if the shops are cutting right down the middle.
I don't know, but I have always preferred half-yard cuts to fat quarters. I just find it is more usable for me. I feel like I am buying a scrap when I buy a FQ.
