Why Proper Threading Matters

Improper threading is the number-one cause of skipped stitches, thread breakage, and tension problems for beginners. The good news: once you've threaded your machine a handful of times, it becomes second nature. This guide walks you through the upper threading process step by step, along with tips for loading the bobbin correctly.

What You'll Need

  • Your sewing machine (with the manual handy if possible)
  • A spool of thread
  • A wound bobbin (same thread is ideal)
  • Good lighting

Part 1: Loading the Bobbin

Before threading the upper section, your bobbin needs to be loaded correctly. Most modern machines use a drop-in (top-loading) bobbin, though some older models use a front-loading style.

  1. Wind your bobbin if it isn't already wound. Place the thread spool on the spool pin, follow your machine's bobbin winding path, and engage the bobbin winder.
  2. Open the bobbin cover (the small plate near the needle, usually sliding or popping off).
  3. Drop in the bobbin with the thread unwinding counter-clockwise (for most machines — check your manual).
  4. Guide the thread through the slot in the bobbin case, pulling it toward you until you feel a slight tension.
  5. Replace the cover, leaving a few inches of thread trailing out.

Part 2: Threading the Upper Machine

Always start with the presser foot raised and the needle in its highest position before threading.

  1. Place the thread spool on the spool pin. Most machines have a horizontal or vertical pin at the top. Use the spool cap to hold it in place.
  2. Guide the thread to the first thread guide. This is usually a small hook or slot near the top of the machine. Follow the arrows or numbered diagram printed on your machine.
  3. Pull the thread down and around the tension discs. The thread should pass through the U-shaped channel on the front of the machine, going down one side and up the other.
  4. Hook the thread through the take-up lever. This is the moving arm with a hole or hook near the top of the machine. Thread it from right to left.
  5. Follow any remaining thread guides down toward the needle. Most machines have one or two small guides near the needle bar.
  6. Thread the needle. Pass the thread through the eye of the needle from front to back (or left to right — check your machine's direction). If your machine has an automatic needle threader, now's the time to use it.
  7. Pull up the bobbin thread. Hold the upper thread loosely, lower and raise the needle once using the handwheel, then gently pull the upper thread — the bobbin thread should loop up through the needle plate. Pull both threads to the back of the machine.

Common Threading Mistakes to Avoid

  • Skipping a thread guide: Every guide serves a purpose. Missing one changes the thread path and causes tension issues.
  • Threading with the presser foot down: The tension discs only open when the presser foot is raised. Always thread with it up.
  • Bobbin inserted in the wrong direction: This is a surprisingly common issue that causes thread jams and skipped stitches.
  • Not pulling both threads to the back before sewing: Starting with threads loose under the needle can cause the thread to bunch underneath your fabric.

A Quick Test Before You Sew

Once threaded, do a quick test on a scrap of fabric. A properly threaded machine will produce even stitches on both sides of the fabric with no loops or puckering. If stitches look uneven, re-thread from scratch — it's almost always a threading issue rather than a tension problem.

With practice, threading your machine will take less than 60 seconds. Don't rush it at first — the habit of doing it carefully is what matters most.
