I have quilted I think all of the different Minky's on my APQS Longarm with no problems. There was one that the gal had gotten I believe at Hancock fabrics that reminded me of fake fur (really long nap)but it really was a minky and when I started with it I wasn't sure about it. But in even quilted up nice. As long as the biggest stretch goes east and west I have never had a problem and really like how the minky looks quilted up.
