The blanket stitch is a straightforward loop that locks thread to fabric edge

A blanket stitch is a hand-sewn loop that runs along the edge of fabric to prevent fraying and finish the edge neatly. The thread wraps around the fabric edge as you stitch, creating a chain of small loops that sit perpendicular to the edge. You work from left to right, pushing the needle through the fabric and catching the working thread in the loop before pulling tight. The stitch takes about 15 to 20 minutes to complete a standard 60-inch blanket edge, depending on your speed and stitch spacing.

The blanket stitch works on any fabric but is most common on fleece, wool, and cotton blankets because these materials fray easily. You can space the stitches close together for a decorative look or farther apart for a functional finish. The stitch is strong enough to hold for years of washing and use, and it looks finished on both sides of the blanket.

Key Takeaways

  • Thread your needle with a single strand of embroidery floss or thread, knot one end, and start from the back of the fabric so the knot stays hidden inside the fold.
  • Push the needle up through the fabric edge, loop the working thread under the needle tip, and pull the needle through to lock the loop against the fabric edge.
  • Keep stitches evenly spaced about one-quarter inch apart and maintain consistent tension so loops sit flat and uniform along the edge.
  • Work slowly on your first blanket—rushing causes uneven loops and loose stitches that pull apart during washing.

What you need before you start

Gather a needle with an eye large enough for your thread, embroidery floss or thread in a color that matches or contrasts with your blanket, scissors, and the blanket itself. A needle size 7 or 8 works well for most blanket stitching. If you are using embroidery floss, separate it into single strands rather than using all six strands together—single strands create neater, more even loops.

Trim any loose threads from the blanket edge with scissors before you begin. If the edge is very frayed, fold it over about one-quarter inch and press it flat with your fingers or an iron. This gives you a clean edge to stitch through and prevents the needle from catching loose fibers as you work.

How to thread the needle and start the first stitch

Cut a length of thread about 18 inches long—longer threads tangle and fray as you work. Thread it through the needle eye and tie a knot at one end. Hold the blanket with the edge facing you and the back of the fabric toward your body. Push the needle through the fold of the fabric edge from back to front, about one-quarter inch from the corner. The knot will stay hidden inside the fold.

Pull the thread all the way through until the knot catches inside the fold. You are now ready to make the first loop. The needle should be coming out of the fabric right at the edge, with the thread hanging down in front of the blanket.

Making the loop stitch step by step

Hold the working thread (the thread hanging from your needle) loosely under your thumb and index finger, forming a small loop below the fabric edge. Push the needle down through the fabric about one-quarter inch to the right of where it came out, staying right at the edge. The needle should pass over the loop of thread you are holding.

Before you pull the needle all the way through, catch the loop of thread under the needle tip. Now pull the needle through the fabric and tighten the thread gently. The loop will lock against the edge of the blanket, creating one stitch. Do not pull too hard—tight stitches pucker the fabric and break the thread.

Move one-quarter inch to the right and repeat. Push the needle down through the fabric, catch the loop under the tip, and pull through. Each stitch should sit perpendicular to the edge, forming a small square or rectangle of thread standing up from the fabric. If your stitches are lying flat against the fabric instead of standing up, you are pulling too tight or not catching the loop properly under the needle.

Keeping stitches even and spacing consistent

The most common mistake is spacing stitches unevenly. Use your needle as a measuring tool—if your needle is about one-quarter inch wide, use that width as your spacing guide. Mark the blanket edge lightly with a pencil every one-quarter inch before you start if you are nervous about spacing. Erase the marks after you finish stitching.

Tension matters more than speed. Stitches should be snug enough that they do not slip when you tug the thread, but loose enough that you can see the loop clearly standing away from the edge. If a stitch looks too loose, you can go back and tighten it by gently pulling the thread, but this takes practice. It is easier to maintain even tension from the start by pulling with the same pressure on every stitch.

Finishing the last stitch and securing the thread

When you reach the corner or end of the blanket edge, make one final stitch. Push the needle through the fabric as usual, but this time do not make a loop. Instead, push the needle to the back of the fabric and bring it out about one-quarter inch away. Pull the thread tight and tie a small knot against the back of the fabric. Trim the excess thread close to the knot.

If you run out of thread before finishing an edge, tie off the thread on the back of the fabric and start a new length with a knot hidden in the fold, just as you did at the beginning. The join will be nearly invisible if you tie off and start within one stitch of each other.

Common mistakes and how to fix them

Loops that lie flat against the fabric instead of standing up mean you are either pulling too tight or not catching the loop under the needle properly. Slow down and watch the needle tip as it passes under the loop. The thread should clearly pass under the needle before you pull through.

Uneven spacing makes the blanket look sloppy even if each individual stitch is neat. Use a ruler or your needle width as a guide, and count stitches as you go. If you notice you have drifted, adjust gradually over the next few stitches rather than jumping back to correct one spot.

Thread that breaks or frays means your needle is too small or your thread is tangled. Use a larger needle and separate embroidery floss into single strands. If thread keeps breaking, you may be pulling too hard—ease up on tension and let the stitch form naturally.

Frequently Asked Questions

Can I use a sewing machine to blanket stitch instead of doing it by hand?

Yes. Most sewing machines have a blanket stitch setting that creates the same loop effect. Set the stitch width to medium and length to medium, and test on a scrap of fabric first. Machine stitching is faster but less forgiving—mistakes are harder to fix than with hand stitching.

What thread color should I use?

Match the blanket color for a subtle, finished look, or choose a contrasting color for a decorative effect. Embroidery floss comes in hundreds of colors and is thicker than regular sewing thread, so it shows up clearly and wears well through washing.

How do I blanket stitch around corners?

At a corner, make your last stitch right at the corner point, then rotate the blanket 90 degrees and continue stitching along the next edge. The stitches will naturally turn the corner without any special technique.

Will the blanket stitch hold up in the washing machine?

Yes, if the stitches are tight and evenly spaced. Wash the blanket in cold water on a gentle cycle and dry it on low heat. The blanket stitch is designed to withstand regular washing and will last for years.

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

A standard 60-by-80-inch blanket takes about two to four hours depending on your speed and stitch spacing. Most people work faster as they develop a rhythm, so your second blanket will be quicker than your first.
