In my experience it seems the higher the price, the more fraying/raveling happens. I am not a quilt shop quilter. I guess I'm still operating on the thoughts of the generations before us that anything can go into a quilt. Those women would be aghast that quilters of today actually buy fabric to cut into pieces for a quilt--and that they pay premium prices for it! I have just finished a little quilt that I found blocks constructed by my mother. There was everything in those. But the box also included a sheet that she apparently intended for the quilt. So it went, too. It is the border and the back. Oh, my--it has a goodly amount of poly in it. I loved it. I like the sheen and it hand-quilted like a dream. Thanks, Mom!
