Sewing a button on jeans takes about five minutes once you have the right supplies

A button on jeans comes loose because the thread holding it wears through from constant movement and friction. You can sew it back on with a needle, thread, and the button itself—no machine needed. The process is the same whether the button fell off completely or is hanging by a thread, and jeans buttons are easier to work with than shirt buttons because they are thicker and sit on a shank (a small stem underneath).

The main difference between sewing a jeans button and a regular button is that jeans buttons take more thread and more passes of the needle because the fabric is thick. You will also want to use thread that matches the original color, though on dark jeans a dark gray or navy works if you cannot find an exact match.

Key Takeaways

  • Jeans buttons have a shank underneath that you thread through, not holes you pass through like shirt buttons.
  • Use a needle, thread that matches your jeans color, scissors, and the button itself—no special tools required.
  • Pass the needle through the shank at least eight times to make the button find enough for daily wear.
  • Wrap thread around the shank underneath the button to create a reinforced base that prevents the button from pulling loose again.
  • Knot the thread on the inside of the jeans fabric so the knot does not show on the front.

What you need before you start

Gather a needle, thread, scissors, and the button. If the button fell off, you should have it. If it is still attached but loose, gently pull it off and set it aside. For thread, use a color that matches your jeans as closely as possible—dark blue, black, or gray depending on your jeans. A single strand of thread is too weak; you will use doubled or quadrupled thread for strength.

If you do not have a needle that fits through the shank hole, a smaller needle works better than a larger one. The shank hole on a jeans button is usually small. If your needle is too thick, try a thinner needle or carefully enlarge the hole by pushing a toothpick through it a few times.

Threading the needle and knotting the end

Cut a length of thread about 18 inches long. Fold it in half, then fold it in half again so you have four strands together. Thread all four strands through the eye of the needle at once. This gives you the thickness you need to hold the button securely.

Pull the thread so the four strands are even, then tie a knot at the end. You want one knot at the very end of all four strands together. Pull the knot tight so it will not slip through the fabric when you start sewing.

Positioning the button and starting the first stitch

Place the button on the spot where it belongs on your jeans. Push the needle up through the fabric from the inside of the jeans, coming out through the shank hole in the button. Pull the thread until the knot catches on the inside of the fabric. The knot should be on the inside of the jeans, not visible from the front.

Once the needle comes through the shank, you are ready to start passing it back and forth. The shank is the small stem under the button—that is what you thread through, not the button itself.

Passing the needle through the shank eight or more times

Push the needle back down through the shank and through the fabric underneath. Pull the thread tight. Push the needle back up through the shank again. Repeat this motion at least eight times. Each pass should be tight enough that you feel resistance, but not so tight that you bend the needle.

Eight passes is the minimum for a jeans button because the fabric is thick and the button takes a lot of stress. If you want extra durability, do ten or twelve passes. You will feel the button getting more solid as you add passes.

Wrapping thread around the shank for reinforcement

After your final pass through the shank, bring the needle up through the fabric but do not go through the shank. Instead, wrap the thread around the shank two or three times, pulling it tight each time. This creates a reinforced base that keeps the button from pulling loose again. The wrapping distributes the stress across more thread instead of concentrating it all in the shank hole.

After wrapping, push the needle back down through the fabric one final time, but not through the button. You are now on the inside of the jeans with the needle ready to tie off.

Knotting the thread on the inside and trimming

On the inside of the jeans, make a small loop with the thread and push the needle through it to create a knot. Pull tight. Make a second knot the same way for extra security. The knots should be on the inside fabric where they will not be seen.

Trim the thread close to the knots with scissors. Leave about a quarter-inch of thread so the knot does not unravel. Your button is now sewn on and ready to wear.

Frequently Asked Questions

What if the button hole in the jeans is torn or enlarged?

If the hole is slightly enlarged, sew the button in the same spot—the extra thread passes will hold it. If the hole is badly torn, move the button slightly to one side where the fabric is intact, or reinforce the area with a small patch of denim fabric glued or sewn underneath before attaching the button.

Can I use a sewing machine instead of hand sewing?

Yes, but hand sewing is faster for a single button. If you use a machine, set it to a zigzag stitch, place the button under the presser foot, and let the needle pass through the shank several times. Lower the presser foot pressure so you do not break the needle on the thick button.

How do I match the thread color if my jeans are faded?

Bring your jeans to a fabric store and hold thread samples next to them in natural light. A slightly darker shade usually looks better than a lighter one on faded jeans. If you cannot find a match, dark gray or navy works on most blue jeans.

What if I do not have the original button?

You can buy replacement jeans buttons at fabric stores or online. Look for a button with a shank and a diameter that matches your other jeans buttons. Bring a pair of jeans or a photo of the button to make sure you get the right size.

How long does a sewn button usually last?

A button sewn with eight or more passes of thread typically lasts as long as the jeans themselves. If a button comes loose again within a few weeks, the original thread may have been weak or the hole may be damaged—resew it with fresh thread or move it slightly to a stronger part of the fabric.
