Thread the machine before you plug it in

Before you turn on your sewing machine, you need to load thread into it. The thread path is the route the thread takes from the spool to the needle, and every machine has a slightly different layout — but the principle is the same on all of them. Check your machine's manual for a diagram showing exactly where the thread guides, tension discs, and take-up lever are located on your model.

Start by placing a spool of thread on the spool pin at the top of the machine. The spool pin is usually a small rod that sticks up; thread the spool onto it so the thread unwinds toward the front of the machine. Then, with the presser foot lever in the up position (this opens the tension discs), guide the thread through each guide and tension point in order, following the diagram in your manual. The thread should pass through the take-up lever — a small hook that moves up and down — and then down through the needle clamp. Finally, thread the needle itself from front to back, leaving a 6-inch tail hanging down.

Once the needle is threaded, lower the presser foot lever. This closes the tension discs and holds the thread in place. If you skip this step, your thread will slip and your stitches will be loose.

Wind and insert a bobbin

The bobbin is a small spool that holds thread underneath the needle plate. Most machines come with several empty bobbins. To wind one, place an empty bobbin on the bobbin winder — a small spindle, usually on the side or top of the machine — and guide thread from your top spool through the bobbin winding guide. Press the bobbin winder against the machine body to engage it, then hold the thread tail and press the foot pedal or press start (depending on your machine type) until the bobbin is full. The winder will stop automatically when it senses the bobbin is wound.

Once the bobbin is wound, remove it and insert it into the bobbin case. The bobbin case is usually a small metal or plastic housing under the needle plate. Open the case, place the wound bobbin inside, and thread the bobbin thread through the tension spring, following your manual's diagram. Close the case and you are ready to sew.

Key Takeaways

  • Thread the top of the machine with the presser foot lever up, following the thread path shown in your manual, and lower the lever when finished to close the tension discs.
  • Wind a bobbin using the bobbin winder on your machine, then insert it into the bobbin case under the needle plate and thread it through the tension spring.
  • Bring up the bobbin thread by turning the hand wheel toward you once, which will pull a loop of bobbin thread through the needle plate.
  • Test your threading by sewing a few stitches on scrap fabric before you start a real project.

Bring up the bobbin thread

After you insert the bobbin, you need to bring the bobbin thread up through the needle plate so both threads are ready to sew. Hold the top thread tail in your left hand. With your right hand, turn the hand wheel (the large wheel on the right side of the machine) toward you one full rotation. As the needle goes down and comes back up, it will catch the bobbin thread and pull a loop up through the needle plate.

Pull gently on the top thread tail and the bobbin thread loop will come up with it. You now have both threads ready. Pull both threads toward the back of the machine and under the presser foot, leaving them loose enough that they do not pull the needle out of position.

Set your stitch length and width

Before you sew, decide what stitch you want to make. Most machines have a dial or digital screen showing different stitch options — a straight stitch is the most common choice for beginners. Once you select your stitch, adjust the stitch length. Stitch length is measured in millimeters; a length of 2.5 mm is standard for most fabrics. If you make the stitches shorter, the seam will be stronger but slower to sew. If you make them longer, the seam will be weaker but faster.

Stitch width applies mainly to decorative stitches and zigzag stitches. For a straight stitch, width does not matter. Check your manual for the recommended settings for the fabric you are using — heavier fabrics like denim usually need a longer stitch length, while lightweight fabrics like cotton voile need a shorter one.

Position fabric and lower the presser foot

Place your fabric under the presser foot, positioning it so the needle will enter the fabric about one-quarter inch from the edge. This one-quarter inch margin is called the seam allowance and is standard in most sewing projects. Lower the presser foot by moving the lever down. The presser foot holds the fabric in place while the needle moves up and down.

If you forget to lower the presser foot, the tension will not engage and your thread will not catch properly — your stitches will be loose loops instead of tight seams. This is one of the most common mistakes beginners make, so double-check before you start sewing.

Sew slowly and guide the fabric

Press the foot pedal gently to start sewing. The machine will move the fabric forward automatically — your job is to guide it in a straight line, not to push or pull. Keep your hands relaxed and let the feed dogs (the metal teeth under the presser foot) do the work. If you push the fabric, you risk breaking the needle or creating uneven stitches.

Sew slowly at first, especially if you are new to sewing. Most machines have a speed control dial or button; set it to a slower speed until you feel comfortable. As you sew, watch the line you are following and make small adjustments to keep the fabric straight. When you reach the end of your seam, release the foot pedal and raise the presser foot to remove the fabric.

Trim threads and remove fabric safely

After you finish sewing, raise the presser foot and pull the fabric toward you to remove it. Leave about 4 inches of thread attached to both the needle and the bobbin — do not cut the threads too short or you will have nothing to hold when you start the next seam. Use scissors or the thread cutter built into the back of many machines to trim the threads.

If your machine has a thread cutter, it is usually a small notch on the back of the presser foot. Pull both threads toward the back of the machine and slide them through the notch to cut them cleanly. If you cut by hand, cut at an angle so the thread ends are sharp and easier to thread on your next project.

Frequently Asked Questions

What do I do if the needle breaks?

Stop sewing when ready and turn off the machine. Raise the presser foot and needle to their highest positions, then unscrew the needle clamp and remove the broken needle. Insert a new needle of the same size and type, making sure it is inserted all the way up into the clamp. Re-thread the machine before you sew again.

Why are my stitches loose or loopy?

Loose stitches usually mean the presser foot was not lowered when you started sewing, or the thread was not threaded correctly through the tension discs. Raise the presser foot, re-thread the top thread following your manual exactly, lower the foot again, and test on scrap fabric. If the problem continues, the bobbin may not be inserted correctly — remove it and reinsert it, making sure the thread passes through the tension spring.

Can I sew different fabrics on the same machine?

Yes, but you may need to change the needle and stitch length. Lightweight fabrics like cotton need a smaller needle (size 60 or 70) and shorter stitch length (2.0 mm). Heavy fabrics like denim need a larger needle (size 100 or 110) and longer stitch length (3.0 to 4.0 mm). Always test on scrap fabric first to make sure the settings work.

How do I know if my machine is threaded correctly?

Sew a few stitches on scrap fabric and look at both sides of the seam. The top thread and bobbin thread should interlock in the middle of the fabric, creating a balanced stitch that looks the same on both sides. If the top thread is loose and loopy, the top threading is wrong. If the bobbin thread is loose, the bobbin is not threaded correctly.

What should I do before I start sewing a real project?

Always test your machine on scrap fabric first. Use the same fabric type and thread you plan to use on your project, sew a few inches, and check that the stitches look even and balanced. This takes two minutes and saves you from ruining your project if something is not set correctly.
