    What to do if the fabric is not feeding smoothly on my Janome Sewing Machine?
    • G
      George GrossAug 28, 2025
      If the fabric isn't feeding smoothly, it could be that the feed dog is packed with lint, the stitches are too fine (make stitch longer), or the feed dog is not raised after “drop feed” sewing.

      If the needle breaks, it could be due to: * Incorrect insertion of the needle. * A loose needle clamp screw. * Failure to draw the threads to the rear after sewing. * Using a needle too fine for the fabric. * Using an inappropriate presser foot. In this case, use the correct foot.

    Why is my Janome M50QDC not sewing buttonholes properly?
    • A
      Adam JohnsonSep 4, 2025
      If buttonholes aren't sewing properly, the stitch density may not be suitable for the fabric, interfacing hasn't been used for stretch or synthetic fabrics (apply an interfacing), or the buttonhole lever isn't lowered.

    Why is my Janome M50QDC Sewing Machine seam puckering?
    • F
      freemanbenjaminSep 10, 2025
      Seam puckering may occur if the needle thread tension is too tight, the needle thread is not threaded properly, the needle is too heavy for the fabric, the stitch length is too long for the fabric (make stitch shorter), or a stabilizer is not used when sewing very fine fabrics (apply a stabilizer).
