I just did a few loads of new fabric laundry last night. When I first started sewing I bought a lot of FQ and constantly complained about fray. My more recent fabric purchases have been yardage and I can say that I have FAR less fraying. Last night not a single piece of fabric was "tied" to any other piece of fabric and I had very few strings on the ones that did have some fray.
Once, a few years ago I made a list of which manufacturers frayed more than others. I'll try to find it.
