I guess I've been lucky with precuts, I buy mostly Moda and a few other major manuf. I haven't had a problem yet !
IMO I don't think the pinked edges are hiding poor quality. Moda has a very fine pinked edge, I'd much rather have that than lots of raveling !
Agree that FQ are all over the place, fabric widths vary - but a FQ should NEVER be less than 18" ! A yard of fabric is 36" ... period !!
