Probably not. I think I would figure out a way to baste it better so it doesn't slip around as much. I'd put more basting stitches into it and do them in a grid. I'd make those basting stitches no larger than 1/2" and do a 2" grid. Are you using a hoop at all? If not, you may wish to try one, it also helps to tame the slip and you can regularly inspect the back but with a hoop, things are pretty smooth. You are also dealing with considerably more loft than you are used to which also gives the impression that it is going to pucker.
