Troubleshooting Tips

Whether you are a more experienced sewist or you’re just getting started, here are a few tips we’d like

to share with you to help keep your sewing easy and fun!

If Thread Loops Are Showing on the Underside of the Fabric

Thread looping on the underside of the fabric is always an indication that the upper thread is not

correctly threaded. This happens when the upper thread is not correctly placed in the tension

mechanism and has not been threaded through the take-up lever. To resolve this, rethread the

machine, making sure to first raise the presser foot lifter and raise the needle to its highest position, so

that the thread can be properly seated in the tension mechanism and take up lever.

If Bobbin Thread Is Showing on the Top of the Fabric

This can be caused if the top thread tension is too tight, or if the bobbin thread is not in the bobbin

case tension. Check that the upper thread is feeding freely without obstruction (like getting stuck

behind the spool cap or getting caught on any rough spots o the thread spool itself). Make sure the

bobbin is correctly seated in the bobbin case (bobbin holder), and check that the upper thread

tension is not set too tightly.

Troubleshooting Tips Whether you are a more experienced sewist or you’re just getting started, here are a few tips we’d like to share with you to help keep your sewing easy and fun! If Thread Loops Are Showing on the Underside of the Fabric Thread looping on the underside of the fabric is always an indication that the upper thread is not correctly threaded. This happens when the upper thread is not correctly placed in the tension mechanism and has not been threaded through the take-up lever.

If Thread Is Shredding Thread can shred when you sew if it is old or poor quality. Thread can also shred if the machine needle is worn out, or if the needle is the wrong style and size for the thread being used. The thread should pass freely through the eye of the needle in order to sew properly. Use threads that have a smooth, even filament.

If the machine is not feeding fabric when you start sewing, it could be that the presser foot lifter has not been lowered before stepping on the foot controller. Lower the presser foot and resume sewing. Another reason the machine may not be feeding fabric is that the feed dogs (or feed teeth) ar e disengaged, so make sure that they are properly engaged for sewing.

If Upper Thread Is Breaking If the upper thread is breaking, it could be that the thread path is obstructed, the machine is not correctly threaded or the upper thread tension is set to tightly. Be sure that the machine is correctly threaded and there are not obstructions (for example, thread ge tting caught behind the spool cap or a “rough spot” on the spool itself). Check also that the upper thread tension control is set correctly (consult your machine manual).

If Stitches Are Skipping If your stitches are skipping on the fabric as you sew, this could be an indication that the needle was inserted incorrectly. Make sure that the needle goes all the way up into the needle clamp and that the flat side (at the top section of the needle) is facing toward the back. Another reason stitches can be skipping is if the needle is the wrong style for the fabric.
PAGE 6
If Stitches Appear Distorted Stitches can appear distorted on the fabric if you are “pushing” or “pulling” the fabric as you sew. Just let the feed dogs (or feed teeth) do the job of drawing the fabric along under the foot. Another reason stitches could appear distorted is if the incorrect presser foot is used. For example, dense stitches usually require the use of either a Satin Foot or Open Toe Foot, so that the stitching can pass freely underneath.

If Fabric Is “Tunneling” or “Puckering” under the Stitches If fabric appears to be pulling together under the stitches, this is a good sign that y ou should use a fabric stabilizer underneath the fabric. Generally, use a tear-away stabilizer for woven fabrics and a cut-away stabilizer for stretch fabrics.
