Is the fabric in your top looser weave? Is your thread size larger? Have you tried a thinner weight thread? Have you tried loosening the tension on the top thread? I think, I would try those things. I did a search, you are not along. Several people mentioned that using a thin batting does help with this issue. Another mentioned they had gotten their minky from a big box store, went and got real minky and no longer had that problem, another one changed the color of the quilting thread to match the backing so the pulled up minky would not be as obvious. One said she prewashed the minky on cold and then tumbled dry on low or air.
