Why is the fabric puckered when sewing with my Brother NS-40 Sewing Machine?

If the fabric is puckering while using your Brother Sewing Machine, ensure that both the upper and bobbin threads are correctly threaded and installed, and that the spool is correctly installed. Check that you're using the appropriate combination of fabric, thread, and needle. Replace the needle if it's bent or blunt. If sewing thin fabrics, use a stabilizer material underneath. Finally, adjust the thread tension as needed.
