I actually just finished quilting a Cal-king size quilt with Minky for the backing on my domestic sewing machine. I can tell you from first hand experience that spray basting is a must! Also do not pull the minky taught at all. You simply want to get it flat and all the wrinkles smoothed out. I also use machingers, a super slider and a halo. I dont think you need to use all those gadgets, they just help me keep from getting all tense. I do recommend the machingers or any glove with grippy finger tips though to anyone trying to FMQ on a domestic. Oh also - don't try to "wing" the tension either. Do a test run on a scrap sandwich.
