Good point. I just spent $15.99 a yard (total almost $60) for a wide backing at a local quilt shop. You would think for that much money that all would be well. It wasn't.
After preshrinking, while pressing, I discovered a whole section of snags, pulls, runs, whatever you want to call them. Nothing I could do about it then as I had already, preshrunk, squared, pressed, etc. Couldn't return it.
I know if I had inspected it carefully, both as she cut it and then turned it over and looked at the other side that I would have seen that. I also know the LQS personnel would have thought I was rather odd and maybe they wouldn't have liked it. But, for $15.99, plus tax, per yard????
