Do a Google search on how to wash and dry minky. So many people use it on baby quilts I doubt they are all lined dried. I would wash on gentle, then when it finishes do another spin to get the extra water out because the gentle cycle may not get much out. Then I would dry on low for about 10-15 minutes then air dry. Minky stretches, so if you just line dry it I would be afraid it would really stretch out of shape. Hopefully someone that uses it will respond. I use fleece couple times - didn't like how it stretches - I understand minky is even worse so have avoided it. It also depends on how tightly quilted the blanket is. That keeps it from stretching a lot.
