Threading Your Kenmore and Getting Ready to Sew

A Kenmore sewing machine works like most home machines: you thread the top and bobbin, set your stitch type and length, and the needle and bobbin thread lock together to form a stitch. The exact location of controls varies slightly between Kenmore models, but the threading sequence is nearly identical across the brand. Before you thread anything, raise the presser foot (the metal piece that holds fabric down) by lifting the lever on the back of the machine. This opens the tension discs so thread can slide through without resistance.

Start with the top thread. Place your spool of thread on the spool pin at the top of the machine—most Kenmore machines have a vertical pin on the right side. Pull thread from the spool and guide it down through the thread guide (a small hook or loop near the top). Continue down to the tension dial, a numbered wheel usually marked 0 to 9. Thread the line through the slot in the tension dial, then down through the take-up lever (a small hook that moves up and down as you sew). From there, thread down through the needle clamp and finally through the needle eye itself, from front to back. The needle should be inserted with the flat side facing the correct direction for your machine—check your manual, as this varies. Once threaded, pull a few inches of thread toward the back of the machine and hold it there.

Key Takeaways

  • Raise the presser foot before threading so the tension discs open and thread slides through freely.
  • Thread the top in order: spool pin, thread guide, tension dial, take-up lever, needle clamp, needle eye.
  • Wind a bobbin on the bobbin winder, insert it into the bobbin case, and bring up the top thread by turning the handwheel once.
  • Set stitch length between 2.0 and 2.5 millimeters for most fabric, and lower the presser foot before you sew.
  • Common problems like skipped stitches or bunching usually come from a dull needle, incorrect threading, or mismatched thread and fabric weight.

Winding and Installing the Bobbin

The bobbin is a small spool that holds thread underneath the fabric. You must wind it before you can sew. Place an empty bobbin on the bobbin winder, a spindle usually on the right side of your Kenmore machine near the top. Put your thread spool on the main spool pin and guide the thread around the bobbin winder tension guide (a small metal piece), then wrap it around the empty bobbin a few times by hand. Push the bobbin winder to the right or engage it—your manual will show the exact motion—and the machine will wind thread onto the bobbin automatically as you press the foot pedal. Stop when the bobbin is full; most machines have a sensor that stops the winding automatically.

Once wound, remove the bobbin and insert it into the bobbin case. On most Kenmore machines, the bobbin case is a removable metal or plastic piece in the bed of the machine, directly below the needle. Open the case by unlatching a small lever or sliding it out. Drop the bobbin in so the thread unwinds in the correct direction—your manual shows this, but usually the thread comes off the bobbin counterclockwise. Thread the bobbin thread through the tension spring in the bobbin case, then close and latch the case. Now turn the handwheel (the large wheel on the right side of the machine) toward you one full rotation. This brings the bobbin thread up through the needle plate. You should see a loop of bobbin thread come up. Pull on the top thread gently and the bobbin thread loop will come through. Pull both threads toward the back of the machine and under the presser foot.

Setting Stitch Type, Length, and Width

Kenmore machines have a stitch selector dial or digital display depending on the model. The straight stitch is the most common and is usually marked with a straight line or the number 1. Turn the dial or press the button to select it. Once you have chosen your stitch, you need to set the stitch length—how far the fabric moves forward with each stitch. For most woven fabrics and everyday sewing, set the length to 2.0 to 2.5 millimeters. Lighter fabrics like cotton voile or silk need a shorter length, around 1.5 to 2.0 millimeters, to avoid puckering. Heavier fabrics like denim or canvas can handle 2.5 to 3.0 millimeters. The stitch length dial or digital readout is usually near the stitch selector.

Some stitches also have a width setting, which controls how far the needle moves side to side. The straight stitch has no width—the needle stays in one place. Decorative stitches and zigzag stitches have width controls. Start with a width of 2.0 to 3.0 millimeters for a zigzag stitch unless your manual recommends otherwise. Lower the presser foot before you sew—this is essential because the presser foot applies tension to the fabric and engages the tension discs on top. Without it lowered, your stitches will be loose and uneven.

Sewing Your First Seam

Place your fabric under the presser foot with the edge aligned to the seam guide (a line etched into the needle plate, usually marking a half-inch seam allowance). Hold both the top and bobbin threads behind the presser foot with your fingers. Press the foot pedal slowly and the machine will begin to sew. The fabric will feed forward automatically—do not pull it. Guide the fabric gently with your hands, keeping the edge aligned to the seam guide. Sew at a steady, moderate speed; pushing the pedal harder does not make better stitches, only faster ones.

When you reach the end of your seam, stop the machine by releasing the foot pedal. Turn the handwheel toward you to raise the needle all the way up, then raise the presser foot. Pull the fabric toward you and snip the threads with scissors, leaving a few inches of thread trailing from both the needle and the bobbin. These thread tails make it easier to start your next seam. If you need to backstitch (sew backward to lock the thread), most Kenmore machines have a reverse button or lever. Press it while sewing to move backward, then release it to move forward again.

Tension Adjustment and Troubleshooting

Tension controls how tightly the top and bobbin threads lock together in the middle of the fabric. If your stitches look loose on top and tight underneath, your top tension is too loose—turn the tension dial to a higher number. If the top thread looks tight and the bobbin thread is loose underneath, your top tension is too tight—turn the dial to a lower number. Most sewing happens at a tension setting of 4 to 6 on a scale of 0 to 9. Make small adjustments, one number at a time, and sew a test seam on scrap fabric after each change.

Skipped stitches usually mean your needle is dull, bent, or inserted incorrectly. Replace the needle—a fresh needle solves this problem more often than any other fix. Bunching or looping of thread at the start of a seam usually means the top thread was not threaded correctly or the presser foot was not raised when you threaded. Rethread the machine with the presser foot up. If thread breaks while sewing, check that the needle is not hitting the presser foot or needle plate, and make sure you are not pulling the fabric. If the machine makes a grinding sound or will not move, stop when ready and check that the bobbin case is inserted correctly and that no thread is tangled around the feed dogs (the metal teeth that move the fabric).

Changing the Needle and Cleaning the Machine

Needles wear out and should be replaced every 8 to 10 hours of sewing, or sooner if you hit a pin or sew over thick seams. Raise the presser foot and turn the handwheel to raise the needle all the way up. Most Kenmore machines have a small screw or latch on the needle clamp. Loosen it and slide the old needle out. Insert a new needle with the flat side facing the correct direction (your manual shows this), push it up as far as it will go, and tighten the screw. Make sure the needle is fully seated or it will break on the first stitch.

Clean your machine every few months or after sewing heavy fabrics. Raise the presser foot and remove the bobbin case. Use a small brush (often included with your machine) to sweep lint and thread scraps from the feed dogs and the area around the bobbin case. Do not use compressed air, which can blow lint deeper into the machine. Oil the machine only if your manual recommends it—many modern Kenmore machines are self-lubricating and do not need oil. If you do oil, use only sewing machine oil and explore just one or two drops to the points your manual specifies.

Frequently Asked Questions

Why does my thread keep breaking?

Thread breaks most often because the needle is dull, bent, or inserted backward. Replace the needle first. If breaking continues, rethread the machine with the presser foot raised—a thread caught in the tension discs will snap under the pressure of sewing. Check that your thread is not old or brittle by testing it on scrap fabric.

How do I fix stitches that look loose and loopy?

Loose loops on the underside of the fabric mean your top tension is too tight. Turn the tension dial down by one or two numbers and sew a test seam. If loops appear on top, your top tension is too loose—turn the dial up. Always test on scrap fabric first.

Can I sew thick fabrics like denim on my Kenmore?

Yes, but use a heavy-duty needle (size 16 or 18) and a longer stitch length of 3.0 to 3.5 millimeters. Sew slowly and do not force the fabric. If the machine struggles, you may need to use a walking foot attachment, which feeds thick layers more evenly.

What should I do if the machine will not sew at all?

Check that the presser foot is lowered, the bobbin is inserted correctly, and the needle is raised all the way up. Make sure the top thread is threaded through every guide and the needle eye. If the machine still will not move, the bobbin case may be jammed—remove it and check for tangled thread or lint.

How often should I replace my needle?

Replace the needle every 8 to 10 hours of sewing, or when ready if you hit a pin, sew over a thick seam, or notice skipped stitches. A fresh needle is the cheapest and most effective fix for most sewing problems.
