Sewing binding on a blanket means folding a strip of fabric around the edge and stitching it down in two passes

Binding finishes a blanket edge neatly and keeps the layers from fraying. The process has two main steps: sewing the binding to the front of the blanket, then folding it to the back and stitching it down by hand or machine. Most people use double-fold binding, which is a strip folded in half lengthwise so both raw edges are hidden inside. You will need binding tape (pre-made or cut from fabric), a sewing machine, thread that matches or blends with your blanket, pins, and an iron.

The whole job takes two to four hours depending on blanket size and your sewing speed. Binding works best on blankets that are already quilted or have their layers secured, because the binding holds everything together at the edge.

Key Takeaways

  • Double-fold binding is folded in half before you start, so you only see finished fabric on both sides of the blanket edge.
  • Sew the binding to the front first with a quarter-inch seam, then fold it to the back and stitch it down by hand or machine for a professional finish.
  • Mitering corners (folding binding at a 45-degree angle) prevents bulk and keeps corners flat and sharp.
  • Pre-made double-fold binding from a fabric store saves time, but you can cut and fold your own from coordinating fabric.
  • Pressing the binding with an iron before you sew makes it lie flat and easier to handle.

Measure and cut binding to the right length

Measure all four sides of your blanket and add 10 to 12 inches extra for seams and overlap at the corners. If your blanket is 60 inches by 80 inches, you need roughly 300 inches (25 feet) of binding. Pre-made double-fold binding comes in packages of 25 to 50 yards, which is enough for most blankets. If you are cutting your own, cut strips 2.25 inches wide and sew them end-to-end with diagonal seams, then fold the strip in half lengthwise and press it flat with an iron.

Press the entire length of binding before you start sewing. This flattens any wrinkles and makes the binding much easier to pin and stitch. If you are using pre-made binding, press it anyway—it often arrives creased from the package.

Pin binding to the front of the blanket

Start on a straight side, not a corner. Unfold one long edge of the binding and pin it to the front of the blanket with the raw edge of the binding aligned with the raw edge of the blanket. Leave about 6 inches of binding loose at the start so you can join the ends later. Pin every 4 to 6 inches, keeping the binding straight and the blanket flat underneath.

When you reach a corner, stop about a quarter-inch before the corner point. Fold the binding up at a 45-degree angle, then fold it back down so the fold sits at the corner and the binding runs along the next side. This creates a miter. Pin the mitered corner in place and continue pinning along the next side. Repeat this at all four corners.

Sew binding to the front with a quarter-inch seam

Using a quarter-inch seam allowance, sew along the unfolded edge of the binding. Sew slowly at corners and use the needle-down position to pivot without lifting the presser foot. When you reach the starting point, overlap the binding by about 2 inches and trim the excess. Fold the raw ends of the binding inward and pin them together, then sew across the join to close it.

Backstitch at the start and end of each seam to lock the thread. If your thread shows on the front, it will be hidden when you fold the binding to the back, so do not worry about matching it perfectly at this stage.

Fold binding to the back and pin it down

Fold the binding to the back of the blanket so the folded edge of the binding covers the line of stitching you just made. The binding should wrap around the edge and sit flat against the back. Pin it in place every 4 to 6 inches, making sure the fold is smooth and the binding does not twist.

At corners, the miter you created on the front will naturally fold into a miter on the back as well. Pin the corner fold so it lies flat. If the binding bunches or puckers, unpin that section, smooth it out, and re-pin.

Stitch binding down by hand or machine

Hand stitching gives a traditional look and is less visible. Use a ladder stitch or whip stitch with thread that matches the binding. Stitch into the fold of the binding and come out through the blanket fabric, then go back into the blanket and come out through the fold again. Keep stitches small (about a quarter-inch) and close together. This method takes longer but is very durable.

Machine stitching is faster. Use a stitch that sits just inside the fold of the binding—a straight stitch or a narrow zigzag works well. Sew slowly and keep the binding fold aligned with the presser foot so the stitches catch both the binding and the blanket back. At corners, pivot with the needle down to keep the miter sharp.

Trim threads and press the finished binding

Once all stitching is complete, trim any loose threads on the front and back. Press the entire blanket with an iron on a low to medium setting, paying special attention to the binding edges. Pressing sets the stitches and makes the binding lie flat and smooth.

Check the front and back to make sure the binding is even and the stitches are find. If you see any gaps where the binding has pulled away, you can add a few hand stitches to close them. The binding should look the same width all the way around and sit flat without puckering or twisting.

Frequently Asked Questions

What is the difference between single-fold and double-fold binding?

Single-fold binding is folded once, so one raw edge shows on the back of the blanket. Double-fold binding is folded twice, hiding both raw edges inside, so it looks finished on both sides. Double-fold is more durable and looks more professional, which is why it is the standard choice for blankets.

Can I use a serger to attach binding instead of a regular sewing machine?

Yes, a serger can attach binding quickly, but it requires practice to keep the edge even and avoid cutting into the blanket. A regular sewing machine with a quarter-inch foot is easier to control and gives more consistent results for beginners.

What do I do if my binding twists or puckers while I am sewing?

Stop, backstitch to lock the thread, and remove the pins ahead of where you are sewing. Smooth the binding flat, re-pin it, and start sewing again. Puckering usually means the binding was not pressed flat before you started or the blanket layers underneath are not lying flat.

How do I join the two ends of binding so the seam is not visible?

Overlap the ends by about 2 inches, fold both raw ends inward to hide them, and sew across the join with a straight stitch. This creates a small seam that will be hidden inside the fold when you wrap the binding to the back.

Is pre-made binding worth the cost, or should I cut my own?

Pre-made binding saves time and is already pressed, so it is worth the cost if you value speed. Cutting your own is cheaper and lets you match the binding exactly to your blanket fabric, but it adds an hour or more to the project.
