it is not the designers fault when a manufacturer does not create the line straight!
and different markets have different quality measures- that's why some lines are so much less expensive in some markets and more in others-
it has nothing to do with the designer
and some shops sell (block printed fabrics) as panals- and cut accordingly- others do not care- and will cut right through a block--or charge extra- also not the designer's fault- it was designed to be purchased with each square whole- that part is directly the shops fault
again nothing to do with the designer
