I have quilted using my embroidery machine and used a mega hoop as well as a large hoop depending on the size of the block. My batting was 80/20 Hobbs and I didn't have any trouble with it shifting. Another project I'm using a product called Battilizer which is a denser type batting but not thick. It works beautifully! I have quilted using backing, batting and top and other times no backing. Either way it works great and I'm very pleased with the results. My machine is a Bernina.
