Thread the needle before you start sewing

Threading a needle is the first step in hand sewing, and it takes practice to do it smoothly. Cut a length of thread about 18 inches long — longer than that and it tangles as you work. Wet the end of the thread slightly between your lips or with a damp fingertip to make it stiffer, then push it through the eye of the needle. If the thread frays and won't go through, trim the end with scissors at a sharp angle and try again.

Once the thread is through, pull it so one end is much shorter than the other — about 2 inches on one side and 16 inches on the other. Tie a knot at the short end by wrapping the thread around your index finger once, rolling it off with your thumb, and pulling tight. That knot stops the thread from sliding all the way through the fabric when you start sewing.

If you are left-handed, hold the needle in your left hand and push the thread through from left to right instead of right to left. The mechanics are the same; only the hand changes.

Key Takeaways

  • Cut thread to about 18 inches, wet the end to stiffen it, and push it through the needle eye at a slight angle.
  • Tie a knot at the short end of the thread so it does not slip through the fabric when you begin stitching.
  • Push the needle through the fabric from the top, then bring it back up a short distance away to create a stitch.
  • Keep stitches small and even — about one-eighth inch long — for seams that hold and look neat.
  • Finish by knotting the thread on the back side of the fabric and trimming the excess.

Push the needle through the fabric in a straight line

Hold the fabric in one hand and the needle in the other. Push the needle straight down through the fabric, starting from the top side. Go through both layers if you are sewing two pieces together, or just one layer if you are mending a single piece. Push until the needle comes out the back, then pull the thread all the way through until the knot stops it.

Now push the needle back up through the fabric about one-eighth inch away from where it came out. This creates one stitch. Pull the thread snug but not tight — if you pull too hard, the fabric will pucker. Repeat this motion: down through the fabric, up through the fabric, down again, up again. Each stitch should be roughly the same length as the one before it.

Use a thimble to protect your finger

A thimble is a small metal or plastic cap that fits over the middle finger of your sewing hand. It protects your fingertip from the needle point when you push the needle through thick fabric. If you are sewing light cotton or linen, a thimble is optional. If you are sewing denim, canvas, or multiple layers, a thimble prevents soreness and makes the work faster.

Wear the thimble on the middle finger of your dominant hand — the hand holding the needle. Push the needle against the thimble instead of your fingertip. It takes a few minutes to get used to the feel, but once you do, you will push the needle through with less effort and less pain.

Keep your stitches small and even

The strength of a seam depends on stitch length and consistency. Stitches that are too long — more than one-quarter inch — leave gaps that can tear open. Stitches that vary wildly in length look uneven and are weaker than uniform ones. Aim for stitches about one-eighth inch long, which is roughly the width of a grain of rice.

To keep stitches even, use your fingers as a guide. After you pull the thread through, place your thumbnail on the fabric where the next stitch should start. Push the needle down right at that spot. This straightforward trick trains your hand to space stitches consistently without measuring.

Finish the seam with a knot on the back

When you reach the end of the seam or run out of thread, bring the needle to the back of the fabric. Make a small loop with the thread, push the needle through the loop, and pull tight. This creates a knot that locks the stitches in place. Repeat the loop and knot one more time for extra security, especially on seams that will get heavy use.

Trim the excess thread with scissors, leaving about one-quarter inch of thread above the knot. If you cut too close to the knot, it may unravel. If you leave too much thread, it looks messy and can catch on things.

Choose the right needle size for your fabric

Needles come in different sizes, and the size you choose affects how easily the needle slides through the fabric. Thin fabrics like silk or cotton voile need a small, fine needle — size 10 or 12. Medium-weight fabrics like regular cotton or linen work well with a size 8 or 9 needle. Heavy fabrics like denim or canvas need a larger needle — size 5 or 6 — because a small needle can bend or break.

If the needle is hard to push through the fabric, the needle is too small. If the needle leaves large holes in the fabric, the needle is too large. A needle that glides through with gentle pressure is the right size. Keep a few different sizes on hand so you can match the needle to the job.

Practice the running stitch first

The running stitch is the simplest and most common hand stitch. It is the one described above: down through the fabric, up through the fabric, down again, in a straight line. Once you can make running stitches that are small and even, you can move on to other stitches like the backstitch, which is stronger and used for seams that need to hold under stress.

Practice on scrap fabric before you sew something you care about. Sew a few lines of running stitches on an old piece of cotton or linen. Pay attention to stitch length and spacing. After a few practice sessions, your hand will remember the motion and the spacing will become automatic.

Frequently Asked Questions

Why does my thread keep knotting up while I sew?

Thread knots when it twists on itself, usually because you are pulling too hard or the thread is too long. Cut your thread to 18 inches or less, and pull gently after each stitch — just enough to snug the thread, not to jerk it. If knots still happen, wet the thread again and straighten it before you start sewing.

How do I thread a needle with very small eyes?

Wet the thread end and trim it at a sharp angle with scissors. If it still will not go through, try a needle threader — a small wire tool that pushes the thread through the eye for you. Needle threaders cost a dollar or two and save frustration on fine needles.

What should I do if the needle breaks while I am sewing?

Stop sewing and remove the broken piece from the fabric. If part of the needle is stuck in the fabric, use tweezers to pull it out. Thread a new needle with the same thread and continue sewing from where you left off. Needles usually break because they are the wrong size for the fabric or because you pushed too hard.

Can I use the same thread for the whole project?

Yes, as long as the thread does not run out. When you get close to the end of a thread length, finish with a knot, trim, and thread a new needle. This prevents the thread from becoming too thin or weak near the end of the stitch.

How tight should I pull the thread?

Pull just tight enough that the stitch sits flat against the fabric with no slack. If you pull too hard, the fabric puckers and the seam becomes stiff. If you do not pull hard enough, the stitches are loose and the seam is weak. A gentle, steady pull is the right amount.
