Threading Your Kenmore and Getting Ready to Sew
Before you sew anything, your Kenmore needs thread in the needle and bobbin. The threading path is the same on most Kenmore models: thread goes from the spool, down through the tension discs, through the take-up lever (the small hook that moves up and down), and finally through the needle. If thread skips the tension discs, your stitches will be loose and uneven.
Start with the presser foot up—this opens the tension discs so thread can slide between them. Place your spool on the spool pin at the top of the machine, then guide thread down the left side of the machine, following the guides and clips marked with arrows or numbers. Most Kenmore machines have these marked clearly on the body. Pull thread through the take-up lever, then down through the needle clamp, and finally through the needle eye from front to back. Leave a 4-inch tail hanging below the needle.
For the bobbin, wind thread onto an empty bobbin using the bobbin winder on the side or top of your machine (location varies by model). Once full, insert the bobbin into the bobbin case under the needle plate. Pull up the presser foot lever, then gently pull the needle thread—this will catch the bobbin thread and bring a loop to the surface. Pull both threads toward the back of the machine and under the presser foot.
Key Takeaways
- Thread must pass through the tension discs with the presser foot up, or stitches will be loose and skip.
- The needle goes in from front to back, and the bobbin sits under the needle plate in a removable case.
- Always lower the presser foot before sewing—it controls tension and prevents the needle from bending.
- Start with a medium stitch length (around 2.5) and adjust only if stitches bunch or spread too far apart.
- Backstitch at the start and end of every seam to lock stitches so they do not unravel.
Selecting Stitch Type and Length on Your Kenmore
Kenmore machines offer different stitch options depending on your model. Most basic models have a dial or lever on the front that selects between straight stitch, zigzag, and a few decorative stitches. Straight stitch is what you will use most often—it sews a line of stitches forward in a single direction and is the strongest seam for everyday sewing.
The stitch length dial is usually separate and marked with numbers or millimeters. A setting of 2 to 2.5 is standard for most fabric and works well when you are learning. Shorter stitches (1 to 1.5) create a tighter seam and are good for curves or delicate work. Longer stitches (3 to 4) are faster but weaker and are best for basting or temporary seams. Do not go below 1 or above 5 unless your manual says otherwise—extreme settings can break the needle or jam the machine.
Stitch width applies mainly to zigzag and decorative stitches. For straight stitch, width is usually set to 0 and does not change. If you are using zigzag to finish raw edges or attach elastic, a width of 2 to 3 is typical. Experiment on scrap fabric first so you see what the stitch looks like before you commit to your project.
Lowering the Presser Foot and Starting Your First Seam
The presser foot holds fabric flat against the feed dogs (the metal teeth under the needle plate that move fabric forward). If you forget to lower it, the machine will not feed fabric and the needle may bend or break. After threading and bobbin setup, place your fabric under the needle with the edge aligned to a seam guide line on the needle plate. Most Kenmore machines have lines marked at 1/4 inch, 1/2 inch, and 5/8 inch from the needle.
Lower the presser foot lever at the back of the machine. You should hear or feel a small click. Now hold both thread tails loosely in your left hand and press the foot pedal gently with your right foot. The machine will begin sewing. Sew forward about 1/2 inch, then press the reverse button (usually a lever or button near the foot pedal) and sew backward over those same stitches. This backstitch locks the thread so it will not come loose. Release the reverse button and continue sewing forward at a steady pace.
Guide the fabric with your hands but do not pull it—the feed dogs do the pulling. Let the machine move the fabric at its own speed. If you pull, you risk breaking the needle or creating uneven stitches. When you reach the end of your seam, backstitch again for about 1/2 inch, then stop and raise the presser foot.
Removing Fabric and Cutting Threads
After you finish a seam, raise the presser foot and slide the fabric out from under the needle toward you. Leave about 4 inches of thread attached to the fabric—do not cut it too short or it may pull out of the needle and bobbin. Use the thread cutter built into the back of the presser foot or use scissors to trim threads close to the fabric.
If your Kenmore has a thread cutter on the presser foot, straightforward slide the threads through the small notch at the back of the foot and pull gently. The threads will snap cleanly. If there is no cutter, scissors work just as well. Trim both the needle thread and bobbin thread, leaving about 1/4 inch tails so they do not slip back through the fabric.
Troubleshooting Common Stitching Problems
If your stitches are loose and loopy on top, the needle thread tension is too loose. Turn the tension dial (usually on the left side of the machine) one number higher and test on scrap fabric. If stitches are tight and puckered, tension is too high—turn the dial one number lower. Make small adjustments and test each time; large jumps make it harder to find the right setting.
If the needle breaks or bends, stop when ready and check that the presser foot is down and the needle is inserted correctly (flat side facing the right direction for your machine—check your manual). A bent needle will not sew and can damage the machine. Replace it with a fresh needle of the same size and type. If stitches skip or miss, the needle may be dull, inserted backward, or the wrong size for your fabric. Needles wear out after 8 to 10 hours of sewing, so replace it if you have been using the same one for weeks.
If fabric does not feed forward, make sure the presser foot is down and the feed dogs are not in the lowered position (some Kenmore models have a switch to raise or lower them for free-motion work). If the machine jams or makes a grinding sound, stop sewing, raise the presser foot, and remove the fabric. Check for thread tangles under the needle plate and clear any lint or thread bits with a small brush.
Winding a Bobbin and Refilling Thread
When your bobbin runs out of thread, you need to wind a new one. Most Kenmore machines have a bobbin winder on the top or side. Place an empty bobbin on the winder shaft and slide it to the right to lock it in place. Guide thread from your spool through a small guide or tension disc on the winder (check your manual for the exact path). Press the foot pedal and the bobbin will spin and fill with thread. The winder will stop automatically when the bobbin is full, or you can stop it manually when the bobbin feels firm and full to the touch.
Remove the full bobbin and place it in the bobbin case under the needle plate. Insert the bobbin so the thread unwinds counterclockwise when you look at it from above. Pull the thread through the slot in the bobbin case—you should feel a slight resistance as it passes through the tension spring. If the bobbin is not threaded correctly, stitches will be loose or uneven on the underside of your fabric.
Cleaning and Basic Maintenance
After every few hours of sewing, brush lint and thread bits out from under the needle plate and around the bobbin area. Use a small soft brush (many Kenmore machines come with one) or an old toothbrush. Lint buildup clogs the feed dogs and can cause the machine to jam or skip stitches. Never use water or oil unless your manual specifically says to do so.
Check the needle before each project. A bent, dull, or damaged needle will break, skip stitches, or damage fabric. Replace it if you see any damage or if you have been sewing for more than a few hours. Keep your machine covered when not in use to keep dust out of the mechanism. If the machine has not been used in several months, wind a bobbin and sew on scrap fabric for a minute or two before starting a real project—this helps loosen any stiff parts.
Frequently Asked Questions
What should I do if my needle keeps breaking?
Check that the presser foot is down before you sew and that the needle is inserted correctly (the flat side should face the direction shown in your manual). A bent needle breaks easily, so replace it with a fresh one. If breakage continues, the needle size may be wrong for your fabric—use a smaller needle for delicate fabrics and a larger one for heavy fabrics.
Why are my stitches loose and loopy?
Loose stitches usually mean the needle thread tension is too loose. Turn the tension dial one number higher and test on scrap fabric. If the problem is on the underside only, the bobbin thread may not be threaded through the tension spring in the bobbin case. Rethread the bobbin and try again.
Can I sew thick fabrics like denim or canvas?
Yes, but use a heavy-duty needle (size 16 or 18) and a longer stitch length (3 to 3.5). Start sewing slowly and do not force the fabric through. If the machine struggles, stop and check that the presser foot is down and the needle is not bent. Thick seams may require you to raise the presser foot slightly to clear the bulk of fabric when turning corners.
How do I know if my bobbin is wound correctly?
A correctly wound bobbin should be full and firm, with thread wound evenly from end to end. If it is lumpy or loose, rewind it. When inserted in the bobbin case, thread should unwind smoothly with slight resistance as it passes through the tension spring. If thread pulls out too easily, the bobbin is not threaded correctly.
What is the difference between straight stitch and zigzag?
Straight stitch sews a line forward and is the strongest seam for joining fabric. Zigzag moves the needle side to side as it sews forward and is used to finish raw edges, attach elastic, or create decorative effects. For most basic sewing projects, straight stitch is what you will use.
