If you are stitching straight lines try not to sew in the same directions. When you finsish a row start sewing at the bottom of the quilt instead of going back to the top. The fabric is not being pushed in the same direction. This really helps if you have a tendency to push or pull on the fabric like me. Also try dividing your quilt into 4 sections mentally. Quilt only one section at a time. I start by sewing the outside of that section first and then quilt inside the rectangle I just created. I also use a 505 spray to adhere the layers together and then add a few pins to help stabalize the fabrics. A walking foot also helps.
