I have terrible luck at Jo'Anns with cuts so.. off grain that when its straigtened I end up with 32 inches and less on some. I do not mean to ... complain but ... its so frustrating. I have said something to the manager once and the response was ... "Well we cut it the way it comes of the bolt". I understand that bolts get wound sometimes really off grain , but they push the badly wound onto the consumer to pay the final price with less useable fabric than was paid for.
I agree the wide cuts really can be problematic.
At the LQS - I think the attempt to not give away , has had a backlash in that sometimes, the fabric comes up short. All of the LQS in my area , do not ever give an extra inch. Have they all forgotten that "good will " toward the customer , is its best investment?
