First I "T" pin the backing to the living room carpeted floor. The place the batting, then the top, carefully smoothing as best I can. Then I shoot it all over with a Micro stitch gun. (can be purchased on line at lots of different places) The little plastic thingies aren't long enough to catch into the carpet but sometimes don't catch all the way either but that little tool is a lifesaver. I can probably "micro stitch plastic thingy" 20 times faster than pinning. AND no broken machine needles either!!!
