Things You'll Need

• Thread
• Sewing needles
• Scissors

Instructions

1. Try another needle size if the stitching is coming out irregularly. Rethread the machine and tighten the upper thread tension. Guide the fabric gently through the machine while sewing and maintain steady pressure and control.

2. Avoid pulling the fabric too hard or too quickly if the needle is breaking. Choose the correct size needle for the fabric and thread. Reset the presser foot.

3. Draw both threads under and in the back of the presser foot, leaving about 4 inches of length, and hold until the stitches are first formed if the thread is starting to bunch up.

4. Use the same size and kind of thread in the upper thread and the bobbin thread and use an underlay of tissue paper if there is puckering.

5. Use the "O" needle if stitches are skipping, and loosen the upper thread tension.

6. Start the stitch at medium speed and loosen the upper thread tension if the upper thread is breaking. Insert a new needle and make sure the needle is correct for the fabric and thread.

7. Adjust the stitch length control lever if fabric is not moving during operation. Place both treads under the foot pressure before commencing the stitch.
