I've had 108 inch banking shrink over 6 inches. And it was a well known name brand cotton quilting fabric from a large well known fabric store. Unfortunately it made it too small on one side for my backing, but I was able to put a strip of other fabric from the front across the top, so I was able to save it. But I was not happy to have the backing laid out with the batting on top trying to figure out why my top didn't fit!
