Without more info (batting type, machine model etc.) I have a couple things I would try/check:
- Ease up on your presser foot pressure. Check your manual to see how to accomplish this.
- Make sure there is no drag on your quilt. It should be supported front back and sides enough so that the machine is able to pull it thru. The quilt sandwich may be dragging in the front. This may cause the backing to get caught but allow the batting & top to move pushing it toward you.
