The basic sequence: thread, bobbin, presser foot, needle down, sew
A sewing machine works by pulling thread through fabric in two directions at once — one thread comes from above (the top thread) and one from below (the bobbin) — and they lock together to form a stitch. Before you sew anything, you need to thread the machine, wind and insert the bobbin, lower the presser foot, and position your fabric under the needle. Once those four steps are done, you can start sewing by pressing the foot pedal or button.
The machine will not stitch if the presser foot is up, even if everything else is threaded correctly. This is the most common reason a new sewer thinks something is broken when it is not. The presser foot holds the fabric steady and engages the tension discs that grip the top thread.
Key Takeaways
- Thread the top thread with the presser foot up and the needle in its highest position, following the path marked on your machine from spool to needle.
- Wind the bobbin on the bobbin winder (a separate spindle on the machine), then insert it into the bobbin case with the thread end pulled through the slot.
- Lower the presser foot before sewing — the machine will not stitch without it down, and this is the most common beginner mistake.
- Place fabric under the needle, lower the needle into the fabric by hand or with the needle-down button, then press the foot pedal slowly to start sewing.
- Backstitch at the start and end of every seam by pressing the reverse button or lever to lock the thread and prevent unraveling.
Threading the top thread: follow the marked path from spool to needle
Raise the presser foot and turn the handwheel (the large wheel on the right side of the machine) toward you until the needle reaches its highest point. This opens the tension discs so thread can pass through. Place the spool of thread on the spool pin at the top of the machine — most machines have one pin, some have two for wider spools.
Follow the threading path marked on your machine's body. You will see small hooks, guides, and slots. The thread goes through each one in order, usually starting at a hook near the spool, then down through a tension dial (a round knob with a slot), then through a guide just above the needle, and finally through the needle eye from front to back. Pull the thread gently as you go so it sits fully in each guide. If the thread is not seated in the tension dial, stitches will be loose or uneven.
Thread the needle by holding the thread steady and pushing it through the eye. If you have trouble seeing the eye, use a needle threader — a small wire loop that comes with most machines. Push the loop through the needle eye, put the thread through the loop, then pull the loop back out. Leave about 6 inches of thread hanging below the needle.
Winding and inserting the bobbin: the lower thread
The bobbin is a small spool that holds the lower thread. Most machines come with several empty bobbins. To wind one, place an empty bobbin on the bobbin winder spindle (a small post, usually on the top or side of the machine). Put the spool of thread on the main spool pin as if you were going to sew, then guide the thread around any guides and wrap it around the bobbin a few times by hand to anchor it.
Press the bobbin winder spindle to the right or engage the bobbin winder clutch — this disengages the main needle so it will not move while you wind. Press the foot pedal or press start, and the bobbin will wind automatically. Most machines stop when the bobbin is full, but watch it the first time. Once full, cut the thread, remove the bobbin, and trim the thread end.
Insert the bobbin into the bobbin case. On most machines, the bobbin case is a small metal or plastic housing under the needle plate (the flat metal plate the fabric sits on). Open the case by unlatching a small lever or sliding a cover. Drop the bobbin in so it spins freely, then pull the thread end through the slot in the case. Close the case. The bobbin thread should now be ready to lock with the top thread when you sew.
Lowering the presser foot and positioning fabric
The presser foot is the metal arm that holds fabric flat against the feed dogs (the metal teeth under the needle that move fabric forward). It must be down for the machine to stitch. Raise it by lifting the lever at the back of the foot, place your fabric under the needle, then lower the lever. You should hear or feel a click.
Position the fabric so the needle will pierce it where you want the seam to start. Most seams start about half an inch from the edge of the fabric. Use the needle-down button (if your machine has one) or turn the handwheel toward you to lower the needle into the fabric by hand. This anchors the fabric so it will not shift when you start sewing.
Starting to sew: backstitch, then move forward
Press the foot pedal slowly — do not jam it down. The needle will start moving up and down, pulling thread through the fabric. The feed dogs will move the fabric forward automatically. Sew forward for about half an inch, then press the reverse button or lever to backstitch (sew backward) for the same distance. This locks the thread at the start of the seam so it will not unravel.
Release the reverse button and continue sewing forward. Guide the fabric gently with your hands, but do not pull it — the feed dogs do the work. Most machines have a seam guide (a line marked on the needle plate) to help you keep a straight line. Sew at a speed that feels comfortable. Faster is not better when you are learning.
When you reach the end of the seam, backstitch again for half an inch, then stop. Raise the presser foot, turn the handwheel to raise the needle to its highest point, and pull the fabric toward you. The machine will cut the thread (or you can cut it by hand with scissors). Leave about 6 inches of thread on both the needle and bobbin for the next seam.
Common mistakes and how to fix them
Stitches are loose or bunched: Check that the top thread is seated all the way in the tension dial and the needle. If the bobbin thread is loose, rewind the bobbin or check that it is inserted correctly. If stitches are bunched, the presser foot may be up — lower it and try again.
The needle breaks: You may be pulling the fabric instead of letting the feed dogs move it, or the needle may be bent. Stop, raise the presser foot, and remove the fabric. Replace the needle if it is bent. Insert a new needle with the flat side facing the correct direction (check your manual — it varies by machine).
Thread keeps breaking: The needle may be inserted backward or upside down. Remove it, check the flat side or groove, and reinsert it correctly. The needle may also be dull or damaged — replace it. Make sure the thread is not tangled on the spool or caught on something.
The machine will not sew at all: Check that the presser foot is down. Check that the top thread is threaded all the way through, including the needle eye. Make sure the bobbin is inserted and the bobbin case is closed. If you just wound a bobbin, make sure the bobbin winder spindle is disengaged (pushed back to the left).
Tension and stitch length: adjusting for different fabrics
Tension controls how tight or loose the stitch is. Most machines have a tension dial (usually numbered 0 to 9) on the front. Start at the middle setting (around 4 or 5). If the top thread is too loose, the bobbin thread will show on top — turn the dial up slightly. If the top thread is too tight, the fabric will pucker — turn the dial down.
Stitch length is how far the fabric moves forward with each stitch. A shorter stitch (around 2.0 mm) is stronger and better for seams. A longer stitch (around 3.5 mm) is faster and better for basting (temporary stitching). Most machines have a stitch length dial or button. Start with the default setting and adjust only if you have a reason to.
Frequently Asked Questions
Why does my thread keep breaking?
Thread breaks most often because the needle is inserted backward, dull, or bent. Remove the needle, check that the flat side or groove faces the correct direction (your manual shows which), and replace it if it looks damaged. Also check that thread is not tangled on the spool or caught under the presser foot.
What does it mean if the bobbin thread shows on top of the fabric?
The top thread tension is too loose. Turn the tension dial up by one or two numbers and test on scrap fabric. If the problem gets worse, turn it back down — you may have the dial going the wrong direction, or the top thread may not be threaded all the way through the tension discs.
Can I sew without backstitching?
You can, but the seam will unravel when you pull on it. Backstitching locks the thread at both ends. If you forget to backstitch, you can tie the thread ends by hand after you remove the fabric, but backstitching is faster and more reliable.
How do I know if my needle is inserted correctly?
Check your machine's manual — the needle goes in with either the flat side or the groove facing a specific direction, and it varies by brand. Insert it all the way up into the needle clamp, tighten the clamp screw, then try to pull the needle down by hand. It should not move. If it slides out, it is not inserted far enough.
What is the difference between a ballpoint needle and a universal needle?
A universal needle works on most woven fabrics and is what comes with most machines. A ballpoint needle has a rounded tip and is made for stretchy fabrics like knits and jersey. Using the wrong needle can cause skipped stitches or broken thread. Start with a universal needle and switch only if you are sewing a specific fabric type.
