Sewing-Machine Troubleshooting Tips
While it’s a good idea to take your machine to a dealer regularly for a tune-up, here are a few fixes for common problems.
Bad stitch quality. Before making any other adjustment, lift the machine’s presser foot and rethread the machine.
Skipping or uneven stitches. Try replacing the needle with a new one. Although some quilters only change a needle when it breaks, a smarter rule of thumb is to insert a fresh needle at the start of every project.
Thread breaking. If you’re using old thread, try a new spool; old thread can become brittle and lose elasticity.
