  Jennifer ColeAug 18, 2025
  The needle thread may break due to several reasons: * The needle thread is not threaded properly. In this case, change the needle. * The needle thread tension is too tight. * The needle is bent or blunt. * The needle is incorrectly inserted. * The needle thread is not set under the presser foot when starting to sew. * The fabric is moved too fast when stitching free motion quilting. * The thread is tangled around the spool. To fix this, use the spool holder.
