It's important to watch carefully for flaws and crooked cuts while they are cutting your fabric.
I went to Joanns yesterday (25 miles away, so I don't go often) and there was a young man cutting. He cut a quarter yard for me, and then he started on the next piece. I looked at that first piece and picked it up and measured it on his ruler. It was only 8". He cut me another piece, of course.
When I got home, I washed all the fabric and realized that all of it was crooked, so I still had less than 9 usable inches. It doesn't matter so much on the 3 and 4 yard pieces, but I like to get what I pay for.
If the store was closer, I would return it.
