different markets have different (quality control measures)
when a line is printed/ran it may be going to 10 different markets- all with different (starting fabric) and price base
so you can find the same (print) in the lqs, joannes and walmart- they may all have the same design but be very different fabric.
after a while you can tell by feel what you like- what you do not like-
it's not all the same fabric- its only the same print on the different fabrics.
when trying to decide if its (good quality) feel comes first- then actually look at the print- often in the (lesser markets) the print may be (off) crooked, the fabric itself may not be straight- panals this is most evident- sometimes the squares are so --- not square-- you will have a problem using them-
so look at the fabric- feel it- and decide what is ok for you and what is not
