The blanket stitch is a straightforward loop that finishes raw fabric edges

A blanket stitch is a hand-sewn loop that wraps around the edge of fabric to prevent fraying and add a decorative border. The thread forms a series of connected loops along the edge, with each stitch anchoring the next one. You work from left to right, and the finished line sits perpendicular to the fabric edge, creating a neat, finished look on both sides.

The blanket stitch works on any fabric — cotton, wool, fleece, felt — and is one of the most forgiving hand stitches to learn. You do not need special tools beyond a needle, thread, and scissors. The stitch is strong enough to hold up to washing and wear, which is why it was originally used to finish the edges of wool blankets.

Key Takeaways

  • Thread your needle with a single strand about 18 inches long, knot one end, and start from inside the fabric so the knot stays hidden.
  • Push the needle through the fabric edge, loop the thread under the needle tip, and pull tight to create each stitch about one-quarter inch from the edge.
  • Space stitches roughly one-quarter inch apart along the edge for a balanced, even appearance.
  • Finish by bringing the needle to the back of the fabric, looping the thread under itself, and pulling tight to lock the final stitch.

What you need before you start

Gather a needle with an eye large enough for your thread to pass through easily. A size 7 or 8 embroidery needle works well for most fabrics. You will also need thread — embroidery floss, pearl cotton, or regular sewing thread all work, though embroidery floss shows up better on light fabrics and gives a more polished look.

Cut a length of thread about 18 inches long. This is short enough to control but long enough to complete a section without running out. If you are using embroidery floss, separate it into two or three strands rather than using all six at once — thinner thread is easier to manage and creates a neater stitch. Tie a knot at one end of your thread.

You will also need scissors to trim thread and a thimble if your fingers are sensitive to needle pricks. A thimble protects the finger you use to push the needle through, especially on thicker fabrics like wool or denim.

How to start the stitch on your fabric

Position your fabric so the edge you want to finish faces you. Bring the needle up through the fabric from the back side, about one-quarter inch from the edge. Pull the thread all the way through until the knot catches on the inside of the fabric. The knot should stay hidden — this is why you start from inside rather than on the surface.

The needle is now on the front of the fabric, and you are ready to make your first loop. The distance from the edge to where you brought the needle up becomes your stitch depth — keeping it consistent (about one-quarter inch) makes the finished line look even.

Creating each loop stitch

Hold the fabric in one hand and the needle in the other. Bring the needle down through the fabric edge, entering right at the fold where the fabric ends. As the needle comes back out on the front side, loop the thread under the needle tip before you pull the needle all the way through. Pull the thread snug — not tight enough to pucker the fabric, but tight enough that the loop sits flat against the edge.

This loop is what gives the blanket stitch its name and its strength. The thread wraps around the fabric edge, locking each stitch in place. Move about one-quarter inch to the right along the edge and repeat: bring the needle down through the edge, loop the thread under the tip, and pull through.

Keep your stitches even in size and spacing. Uneven stitches are not wrong, but they are visible. If you find yourself making stitches too tight, loosen your grip slightly — the thread should slide smoothly through the fabric without resistance.

Turning corners and working around curves

At a corner, make one stitch right at the corner point, then rotate your fabric and continue along the next edge. The corner stitch anchors both edges and keeps the line from pulling apart. On curved edges, take slightly smaller stitches on the inside of the curve and slightly larger ones on the outside — this prevents bunching and keeps the line smooth.

If you are working around a circular edge, like the perimeter of a round blanket, the principle is the same: adjust stitch size slightly to follow the curve without puckering. Practice on scrap fabric first if curves feel awkward.

Finishing and securing the last stitch

When you reach the end of the edge or run out of thread, bring the needle to the back of the fabric. Make a small stitch in place, then loop the thread under the needle and pull tight. This creates a lock stitch that prevents the thread from unraveling. Trim the excess thread close to the fabric.

If you need to continue with a new length of thread, tie a knot at the end of the old thread on the back side of the fabric, then start a new thread the same way you started the first one — from inside the fabric with a hidden knot. The knots on the back will not show when the blanket is used.

Common mistakes and how to avoid them

The most common mistake is making stitches too tight, which puckers the fabric edge and makes the line wavy. Loosen your grip and let the thread slide through smoothly. The second mistake is spacing stitches unevenly, which makes the finished edge look sloppy. Mark your spacing lightly with a pencil before you start if you struggle with consistency.

A third mistake is skipping the loop under the needle. If you forget to loop the thread under the needle tip before pulling through, you create a regular running stitch instead of a blanket stitch. The loop is what makes the stitch strong and decorative — do not skip it. Finally, do not pull the thread so tight that it distorts the fabric edge itself. The fabric should lie flat, not curl or bunch.

Frequently Asked Questions

Can I use a blanket stitch on a sewing machine?

Yes. Most modern sewing machines have a blanket stitch setting in their stitch menu. Set the machine to blanket stitch, adjust the width and length to your preference, and sew along the edge. Machine blanket stitches are faster and more uniform than hand stitching, though hand stitching gives a more handmade appearance.

What thread color should I use?

Match the thread to your fabric for a subtle look, or choose a contrasting color to make the stitch a design feature. Embroidery floss comes in hundreds of colors and shows up clearly on most fabrics. Test on a scrap first if you are unsure whether the color will work.

How do I fix a mistake in the middle of the blanket stitch?

If you notice a mistake a few stitches back, you can pull the thread out and redo those stitches. Gently pull the thread to unravel back to the mistake, then re-stitch that section. If the mistake is far behind you, it is usually not worth the effort — the blanket stitch is forgiving enough that small imperfections disappear in use.

Do I need to pre-mark the stitch line?

No, but lightly marking with a pencil helps if you want perfectly even spacing. For most blankets, eyeballing the distance is fine. The blanket stitch is meant to look handmade, so slight variation in spacing is normal and acceptable.

How long does it take to blanket stitch an entire blanket edge?

A standard blanket edge takes several hours of hand stitching, depending on the blanket size and your speed. Most people stitch for 20 to 30 minutes at a time before their hand gets tired. If speed is important, a sewing machine blanket stitch finishes the same edge in 15 to 20 minutes.
