I have used minky on several quilts and have done both FMQ and using a walking foot and have had not trouble...
One did not have batting because my grandson lives in Key West so I just did cross hatching about 3 to 4 inches apart with a walking foot and it came out great. I did use batting in one with a yellow minky background and FMQd with a matching thread and you could barely see the quilting on the back side. Other than the fuzzies you get from cutting, I like working with minky.
