Blanket stitch is a straightforward looped stitch that finishes raw edges and prevents fraying

Blanket stitch is a hand-sewn loop that sits along the edge of fabric, catching both the edge and the body of the material in one motion. The stitch creates a finished border that looks intentional rather than rough, and it actually strengthens the edge so it won't unravel over time. You work from left to right along the edge, pulling the thread through in a way that the loop catches the needle before you tighten it. Once you understand the motion, it takes about five minutes to stitch an edge on a small blanket or pillowcase.

The blanket stitch has been used for centuries to finish the edges of woven blankets and quilts, and it remains one of the most practical hand stitches because it serves both a decorative and protective purpose. Unlike a straightforward running stitch, the loop sits visibly along the edge, so you can choose thread colors that complement or contrast with your fabric. The stitch is forgiving—if you make a mistake, you can straightforward tie off and start again a stitch or two before the error.

Key Takeaways

  • Blanket stitch works by looping thread around the needle before pulling it tight, so the loop sits along the fabric edge and prevents fraying.
  • You need a needle, thread (embroidery thread shows the stitch better than regular thread), scissors, and fabric with a raw edge you want to finish.
  • The stitch moves left to right, with each loop sitting about one-quarter inch from the last, and the depth of each stitch should match the distance between them.
  • The most common mistake is pulling the thread too tight before the loop catches the needle, which breaks the stitch and leaves gaps.

What you need before you start

Gather a needle with an eye large enough for your thread, a length of thread (embroidery thread in a contrasting color shows the stitch clearly, but regular thread works), small sharp scissors, and the fabric edge you want to finish. If you are working on a blanket, cut a length of thread about as long as your arm—long enough to stitch several inches without running out, but short enough that it does not tangle as you work.

Thread the needle and tie a knot at the end of the thread. You will start with the knot on the underside of the fabric, so the first stitch pulls the thread from back to front and hides the knot inside the fold of the edge. If you are new to hand sewing, practice threading the needle a few times before you begin—a steady hand makes the first stitch easier, and the rest follows naturally.

How to make the first stitch

Position the fabric so the raw edge faces you. Bring the needle up through the fabric about one-quarter inch from the edge, so the needle comes out on the front of the fabric. Pull the thread all the way through until the knot catches on the underside.

Now insert the needle back into the fabric at the very edge, right where the raw edge begins. Push the needle through the fabric so it comes out again about one-quarter inch to the right of where you just went in, and about one-quarter inch down from the edge. Before you pull the thread all the way through, loop the thread around the needle shaft—the part of the needle between the point and the eye. Hold the loop loosely with your thumb and finger, then pull the thread through. The loop will catch on the needle and sit along the edge as you tighten it.

Repeating the stitch along the edge

Once the first stitch is complete, you have a small loop sitting at the edge of the fabric. The next stitch begins where the last one ended. Insert the needle at the edge again, right next to the previous stitch, and bring it out one-quarter inch to the right and one-quarter inch down. Loop the thread around the needle again before pulling through.

Keep the spacing even—each stitch should be the same distance from the last, and the depth (how far down into the fabric you go) should match the distance between stitches. If you space them one-quarter inch apart, go one-quarter inch deep. This creates a neat, uniform line. Work your way along the entire edge, keeping the loops snug but not so tight that they distort the fabric. As you develop a rhythm, the motion becomes automatic and you can work faster without sacrificing neatness.

When you reach the end of your thread length, tie off on the underside of the fabric with a small knot, then thread a new needle and continue. Hide the knot inside the fold of the edge so it does not show on the front.

Corners and curves

At a corner, you may need to adjust the spacing slightly so the stitch turns smoothly. When you reach the corner, make one stitch right at the point, then continue along the next edge. If the corner is very sharp, you might place two stitches close together at the corner point to fill the angle, then resume normal spacing on the next side.

On curved edges, the stitch follows the curve naturally as long as you keep the spacing consistent. Gentle curves need no adjustment. Very tight curves may require slightly closer stitches on the inside of the curve to keep the loops from bunching, but this is a minor adjustment and comes with practice. The key is to keep your eye on the spacing rather than trying to force the stitch into a perfect shape.

Common mistakes and how to fix them

The most frequent error is pulling the thread tight before the loop catches the needle. If you pull too fast, the loop slides off and you end up with a gap instead of a stitch. The fix is to slow down: loop the thread around the needle, hold the loop in place with your thumb, then pull the thread through. The loop should tighten as you pull, not before. This is the single most important technique to master, and it becomes second nature after a few stitches.

Another common issue is uneven spacing, which makes the edge look sloppy. If you notice the stitches are drifting closer together or farther apart, stop and look at the last few stitches. Adjust the next one to bring the spacing back to where it should be. A ruler or measuring tape placed alongside the edge can help you keep the distance consistent, especially on your first few projects. If a stitch tears or breaks as you work, straightforward tie off the thread on the underside, thread a new needle, and start again a stitch or two before the break. The overlap will not show on the front.

Finishing the last stitch

When you reach the end of the edge, make your final stitch and pull the thread through completely. On the underside of the fabric, bring the needle up through the loop of the last stitch, then back down through the fabric to create a small anchor knot. Pull tight and trim the thread close to the fabric. This knot will not show on the front and will hold the last stitch in place.

Step back and look at your finished edge. The loops should sit evenly along the border, and the raw edge should be completely covered. If you see any gaps or loose spots, you can go back and add a stitch or two to fill them in. With practice, your blanket stitch will become faster and more uniform, and the finished edge will look polished and professional.

Frequently Asked Questions

What thread should I use for blanket stitch?

Embroidery thread or floss shows the stitch most clearly and comes in many colors, so you can match or contrast with your fabric. Regular sewing thread works too, though it is thinner and the stitch is less visible. Avoid very thick thread on delicate fabrics, as it can pucker the edge.

How deep should each stitch go into the fabric?

The depth should match the distance between stitches. If you space them one-quarter inch apart, go one-quarter inch deep. This creates a balanced look. On very thick fabrics like blankets, you may go slightly deeper—up to three-eighths inch—without problems.

Can I use blanket stitch on curved edges?

Yes. Blanket stitch follows curves naturally as long as you keep the spacing even. On very tight curves, you may need to place stitches slightly closer together on the inside of the curve to prevent bunching, but this is a minor adjustment.

What if I make a mistake in the middle of the edge?

Tie off the thread on the underside, thread a new needle, and start again one or two stitches before the mistake. The overlap will not show on the front. You can also carefully pick out the bad stitches with a seam ripper if you prefer to remove them completely.

Do I have to knot the thread at the start and end?

Yes. The knot at the start hides inside the fold of the edge on the underside. At the end, a small anchor knot through the last loop holds the stitch in place. Both knots stay hidden on the back of the fabric.
