Start by threading your machine correctly—missteps here can throw tension off entirely. Use the tension dial to adjust the top thread tension; higher numbers tighten, lower numbers loosen.

For bobbin tension, give the thread a tug—if the case drops slightly, it’s just right. Too loose? Tighten the tiny screw on the bobbin case. Too tight? Loosen it.

Always test on scrap fabric first. Tension issues often stem from incorrect threading or mismatched thread and fabric, so double-check those, too!

Key Takeaways

  • Double-check your threading—it’s often the root cause of tension issues. Raise the presser foot to seat the thread into tension discs properly.
  • Use the tension dial to adjust top thread tension and the bobbin case screw for bobbin tension. Test on scrap fabric to find the right balance.
  • Match thread weight, type, and fabric to avoid uneven stitches. Thicker threads need looser tension, while thinner threads need tighter settings.
  • Clean tension discs regularly to remove lint and inspect for damaged parts like bent needles or worn bobbins to keep your machine running smoothly.

Thread Tension Basics
