I love Minky its soooo soft and cuddly. I don't know about a rag quilt, never tried that. But I will tell to be ready.. it sheds when you cut it (some types more than others) I had to vacuum a lot in and out of my machine. I machine quilted mine and didn't have any problems. Stitch in the ditch and straight line.. not sure how FMQ would go. Good luck
