If you are using a domestic sewing machine, I believe the only hope you have of quilting it is to quilt it upside down with the minky on the top. Otherwise, as you move the quilt, the minky will most likely shift. I sewed some small simple pillowcase with eggcrate foam and it worked to give comfort to a disable person in a wheel chair but it looked like a toddler had sewn it from the shifting of doing a rolled seam!! On a long arm, you are not moving the quilt but instead moving the sewing machine over the quilt so I think doing it that way is possible. There have been post on this subject. Try doing an ADVANCE search and type in Minky and select posts. Good Luck !!
