3. Thread bunching up under your fabric when sewing
Reasons:
1. Tension seems to be the culprit in the majority of cases.
2. When sewing, the top, and bottom stitches should interlock smoothly
and look the same.
3. Low-quality threads and Loose fiber.
Remedy:
1. Always thread the sewing machine with the presser foot up.
2. Complete engagement is necessary so that the discs can snugly
“grasp” the thread.
3. Tighten or loosen the tension as necessary.
4. Make sure you are using the proper needle for the fabric you are
using.

4. Bent or broken needles
Reasons:
1. Thread Catches on the Spool.
2. Thread Wraps Around the Spool Cap.
3. Thread Wraps Itself Around a Thread Guide More Than Once.
4. Sewing Machine Needle Too Small
5. The Needle Screw is Not Tight Enough.
Remedy:
1. Avoid pulling the fabric.
2. Clean your sewing machine.
3. Check the needle regularly.
4. Use a high-quality sewing machine needle.

5. Fabric not feeding
Reasons:
1. Thread Tension Is Too Tight.
2. Stitch Length Is Set to Zero.
3. Feed Dogs Are Down.
4. Feed Dogs Are Worn.
5. Feed Dogs Are Jammed.
Remedy:
1. Check to see if the feed dogs are up.
2. Be sure that the darning plate is not installed on
the needle plate.
3. Check to see if the thread is tangled.
4. Insert a new needle; making sure the flat side of
the needle is toward the back.

6. Thread keeps breaking
Reasons:
1. Incorrect or damaged needle.
2. Bad thread.
3. Old Thread.
4. Upper tension is too tight.
5. Bobbin tension is too tight.
6. Burrs on the hook assembly.
Remedy:
1. Clear your thread path.
2. Make sure to use the right thread for the project you
are working on.
3. Use the right needle for you’re the fabric and
technique you are using.
4. Check your bobbin and case for any fly away
pieces from previous quilting projects.
5. Check your throat plate, which is sometimes called
a needle plate.

7. Machine is skipping stitches
Reasons:
1. Irregular thread tension on the upper or lower loop.
2. Due to needle deflection.
3. If needle thread loop size is too small.
4. If the sewing thread is unable to form a loop.
Remedy:
1. Needle Size and thread should be adjusted.
2. The thread should be changed.
3. The needle should be changed.
4. The tension of the thread should be adjusted.

8. Bobbin tension not consistent
Reason:
1. Wrong Type of Bobbin
2. Bobbin Thread is Low or Out
3. Bobbin is Overwound
4. Bobbin Case Not Properly Inserted into the Machine
5. Bobbin Tail Too Short
6. Improper Bobbin Tension or Dirty Bobbin Case
7. Damaged Bobbin Case
Remedy:
1. always ensure that you have the right bobbin.
2. To adjust the tension of your bobbin thread.
3. Right thread quality.

9. Sewing machine seizes up or won't sew
Reasons:
1. The machines top thread may not be threaded correctly.
2. Make sure the needle thread is behind the needle bar thread
guide on the needle bar.
3. The thread may be knotted or tangled.
4. The thread may be too thick for the needle.
5. Check that the upper thread tension is not too tight
Remedy:
1. A sewing machine will automatically stop working (or it simply
won’t sew at all) if the bobbin winding mode is ON.
2. We need to make sure that the foot control is completely free
of obstruction. Surely, any obstruction can cause the sewing
machine to seize up or refuse to start working.

10. Needle comes unthreaded before sewing
1. There are knots or tangles in the thread. Remove the knots or
tangles and rethread.
2. The upper thread tension is too tight. Reduce the upper
tension.
3. The thread is tangled in the bobbin case. Remove the tangled
thread.
4. The needle is bent or has a burr on the end of the needle.
Replace with a new needle.
Reasons:
Remedy:
1. Thread the upper thread correctly
2. Reduce the upper thread tension
3. Remove any tangles from the thread
4. ​Install the needle the right way
5. ​Change the needle if it’s bent or broken

11. Fabric feed is inconsistent
Reasons:
 Machine is older, it's possible the feed dogs may have
worn down enough that they aren't catching the
fabric evenly.
 Uneven feed, and the culprit, not surprisingly, is usually the
feed dogs.
Remedy:
• It is the low pressure that causes the fabric to lose
proper contact with the feed dogs, resulting in an
inconsistent feed.
• Clean the area around the feed dogs well

12. Machine is making strange noises
Reasons:
1. Those noises are a signal that something is jammed or rubbing.
2. Bobbin Case Is Full of Lint.
3. Needle Is Damaged, Bent, or Dull.
4. Needle Plate Screw Is Loose.
Remedy:
1. The most common solution to a squeaky sewing machine is oil.
2. Clear Bobbin Case Is Full of Lint.
3. Use high quality needle

13. The machine is running, but the needle won't move
Reasons:
• A disengaged clutch, broken drive belt or internal drive
gear failure can prevent the needle from moving.
• Engage the hand wheel clutch if you have it disengaged
for bobbin winding.
Remedy:
• Ultimately, we can oil our sewing machines after referring to
the manual. In some cases, we may need to seek expert
help in order to lubricate the sewing machine.
• Inspect the sewing machine for lint or thread jam

14. Seams are puckered and distorted
Reasons:
1. Tension pucker is caused while sewing with too much
tension, thereby causing a stretch in the thread. After
sewing, the thread relaxes.
2. As it attempts to recover its original length, it gathers up
the seam, causing the pucker, which cannot be
immediately seen and may be noticeable at a later
stage.
Remedy:
1. Reduce the tension applied to the thread while it is being
wound onto the lock stitch bobbin.
2. Set the needle thread tension to be as light as possible
while achieving a balanced stitch at the same time.
3. Use a high-quality sewing thread with a low-friction
lubricant applied to it.
