I use painter's tape to hold my backing nice and tight and then I spray baste the batting. I leave a 2" border around my batting on all 4 sides. I then spray baste my quilt top on top of the sandwich and the top is 1" smaller than the batting all around. After I spray it I use a rolling pin to get it nice and smooth. It holds up but if you need to adjust it you can take it apart to adjust and when you put it back together just use your rolling pin and it sticks just great. Make sure you have good ventilation and use a drop cloth or be ready to scrub your floor; it gets very tacky.
