In UK we have a cheap fabric shop called abakhan. I was told by a QSOwner they sold cheap fabric. They have a section of craft fabric pieces,where I have been known to shop. Recently at a course the teacher said it was very good quality fabric I had where did I buy it should I tell the truth? I must admit I am very careful what I buy. But I do find some shops have the same differences in quality.
Look but mainly feel the fabric it tells you a great deal.
