I love Minky backing on my quilts. I don't LA myself, but my friend who does says, "no problem," and they never have been. She used pantos, and the quilts have always been wonderful - no tufts of Minky coming through no stretching problems. My guess is that there are many differing qualities of what we call "Minky." I have always used the ones that cost about $16-$17/yd at my LQS. I would guess that the cheaper ones might be more problematic.
