Threading the Machine and Winding the Bobbin
Before you sew anything, your machine needs thread in two places: the top (where you thread the needle) and the bottom (in the bobbin). Start with the bobbin, which is the small spool that holds thread underneath the needle plate. Place an empty bobbin on the bobbin winder pin—a small rod on the side or top of your machine—and guide thread from your main spool through the bobbin winder tension disc. Wind the bobbin by pressing the foot pedal or turning the handwheel until the bobbin is full, then cut the thread and remove it.
Now thread the top of the machine. Raise the presser foot (the metal piece that holds fabric down) all the way up—this opens the tension discs that grip the thread. Place a spool of thread on the spool pin at the top of the machine. Guide the thread down through the thread guides (small metal loops or hooks) and into the tension assembly, following the path marked on your machine. Thread the needle from front to back, leaving a 6-inch tail hanging down. Insert the bobbin into its case under the needle plate, then pull the top thread gently to bring up a loop of bobbin thread. Pull both threads to the back and left of the presser foot.
Key Takeaways
- Wind the bobbin first, then thread the needle from the top, always with the presser foot raised so the tension discs open.
- Bring up the bobbin thread by pulling the top thread gently after inserting the bobbin, then hold both threads behind the presser foot.
- Place fabric under the presser foot, lower the foot, and use the handwheel to lower the needle into the fabric before pressing the foot pedal.
- Stitch in a straight line by guiding the fabric with your hands, not by turning the handwheel—the foot pedal controls the needle speed.
- Backstitch at the start and end of every seam by pressing the reverse button while sewing a few stitches, which locks the thread and prevents unraveling.
Positioning Fabric and Lowering the Needle
Place your fabric under the presser foot so the needle will pierce it where you want to start sewing. Align the fabric edge with one of the guide lines marked on the needle plate—these lines show you how far from the edge the needle will stitch. The most common guide is the 5/8-inch line, which is the standard seam allowance in sewing. Lower the presser foot by pushing down the lever at the back of the foot. This step is essential: the presser foot holds the fabric steady and engages the tension discs.
Before you press the foot pedal, use the handwheel (the large wheel on the right side of the machine) to lower the needle into the fabric by hand. Turn the handwheel toward you until the needle goes down and comes back up. This positions the needle correctly and prevents it from skipping or breaking when you start sewing. Once the needle is in the fabric and the presser foot is down, you are ready to sew.
Starting to Sew and Using the Foot Pedal
The foot pedal controls how fast the needle moves. Press it gently with your foot to start sewing—the harder you press, the faster the machine sews. Many beginners press too hard and lose control of the fabric. Start slowly, especially when learning. Guide the fabric with your hands, but do not pull it toward you or push it away; let the feed dogs (the metal teeth under the presser foot) move the fabric forward at their own pace. Your job is to steer, not to force.
Keep your eyes on the guide line on the needle plate and try to keep the fabric edge aligned with it. This keeps your seam straight and the same distance from the edge all the way down. If you need to stop and reposition the fabric, lift the presser foot (which disengages the feed dogs so the fabric will not move), adjust the fabric, lower the foot again, and continue sewing.
Backstitching to Lock Your Seams
At the beginning and end of every seam, you need to backstitch—sew backward a few stitches to lock the thread so it does not unravel. When you start sewing, sew forward about 1/2 inch, then press and hold the reverse button (usually marked with an arrow pointing backward) while you sew backward to the starting point. Release the reverse button and sew forward again. This creates a locked knot at the start of your seam.
When you reach the end of the seam, press the reverse button again and sew backward about 1/2 inch, then release the button and sew forward one more stitch to finish. This locks the thread at the end. After backstitching, raise the presser foot and pull the fabric away from the needle. The machine will cut the thread tails automatically, or you can trim them with scissors.
Changing Stitch Length and Type
Most machines have a dial or digital display that controls stitch length—how far the needle moves forward with each stitch. A shorter stitch (around 1.5 to 2.0 millimeters) creates a tighter seam and is good for most everyday sewing. A longer stitch (around 3.0 to 4.0 millimeters) is useful for basting (temporary stitching) or sewing thick fabrics. Turn the dial or use the buttons to change the length before you start sewing; changing it while the needle is moving can break the needle.
Your machine also has different stitch types—straight stitch, zigzag, and decorative stitches. The straight stitch is what you use for most seams. The zigzag stitch is useful for finishing raw fabric edges so they do not fray. Select the stitch you want using the stitch selector dial or screen, then sew as normal. Always test a new stitch on scrap fabric first to see how it looks and make sure the tension is correct.
Adjusting Tension When Stitches Look Wrong
If your stitches look loose or bunched, the tension may need adjustment. Tension controls how tightly the top and bottom threads are pulled together. A tension dial on the front of the machine usually shows numbers from 0 to 9, with 4 or 5 as the default middle setting. If the top thread is too loose (stitches look like loops on the bottom), turn the dial to a higher number. If the bottom thread is too loose (stitches look like loops on top), turn the dial to a lower number.
Make small changes—move the dial by half a number at a time—and test on scrap fabric after each change. Most tension problems come from threading mistakes, so re-thread the machine completely before adjusting the dial. If you are sewing very thick or very thin fabric, you may need to adjust tension slightly, but for most everyday sewing, the default setting works fine.
Removing Fabric and Cleaning Up
When you finish sewing, raise the presser foot and pull the fabric away from the needle. If the thread tails are long, trim them with scissors or use the thread cutter built into some machines. Raise the needle to its highest point by turning the handwheel, then remove the fabric completely. If you need to remove the bobbin to refill it, raise the presser foot, open the bobbin case (usually by sliding a latch), and lift out the bobbin.
After sewing, leave the presser foot raised so the tension discs stay open and the thread does not get permanently creased. If you will not be sewing for a while, remove the thread from the machine and store it on the spool. Dust the feed dogs and bobbin area with a small brush to remove lint and thread scraps—lint buildup can cause skipped stitches and tension problems. Most machines do not need oil, but check your manual to see if yours does.
Frequently Asked Questions
Why does my needle keep breaking?
Needles break when they hit the presser foot or bobbin case, usually because the needle is not inserted all the way or is bent. Always insert the needle fully into the needle clamp and make sure it is straight. Also check that you are using the correct needle size for your fabric—a needle that is too thin for thick fabric will bend and break.
What should I do if the thread keeps tangling underneath?
Tangled thread usually means the bobbin is not inserted correctly or the top thread is not threaded properly. Remove the bobbin and reinsert it, making sure it clicks into place. Then re-thread the top of the machine completely, with the presser foot raised. Test on scrap fabric to see if the problem is fixed.
How do I sew a straight line without a guide?
Use the guide lines on the needle plate as your reference. You can also place a piece of tape on the needle plate at the distance you want from the needle, then align your fabric edge with the tape. Some machines have a seam guide attachment that clips onto the presser foot to help you keep a straight line.
Can I sew backwards without the reverse button?
No—always use the reverse button to backstitch. Sewing backwards without pressing the button can jam the machine or break the needle. The reverse button tells the machine to move the feed dogs backward, which is the safe way to sew in reverse.
What is the difference between the handwheel and the foot pedal?
The handwheel lets you move the needle by hand, one stitch at a time, and is useful for positioning the needle or sewing very slowly. The foot pedal controls automatic sewing at whatever speed you press. Always use the handwheel to position the needle before you start sewing with the foot pedal.
