When you place your fabric under your sewing foot. Make sure it is lined up on the edge of the fabric, exactly matching. Then you can adjust your needle position to 1/4 inch. Take a piece of blue painter's tape and place it up to the sewing foot smoothing out the back and front. This will help you to keep your fabric straight when gliding it through the sewing process. You can then adjust your fabric as it sews making sure not to go over the tape. I did this for my daughter and it helped her a lot. Good luck.
