Sew the binding to the front of the quilt first, then fold it to the back and stitch it down by hand
Quilt binding is the fabric strip that finishes the raw edges of your quilt. You cut it on the bias (at a 45-degree angle to the grain), sew it to the front of the quilt with a ¼-inch seam allowance, then fold it over to the back and hand-stitch it in place. The whole process takes a few hours for a lap quilt, longer for a bed-sized quilt. Most quilters use a 2¼-inch-wide strip, which gives you enough fabric to wrap around the quilt edge and still have room to stitch.
The binding is the last step after you have quilted the three layers together and trimmed the quilt to size. It covers the raw edges where the front, batting, and backing meet, and it protects those edges from fraying. A well-sewn binding lasts as long as the quilt itself.
Key Takeaways
- Cut binding strips on the bias at a 45-degree angle, join them end-to-end with diagonal seams, and press the strip in half lengthwise before sewing it to the quilt.
- Sew the binding to the front of the quilt with a ¼-inch seam allowance, stopping ¼ inch before each corner and using a diagonal fold to turn the corners neatly.
- Fold the binding to the back of the quilt and hand-stitch it down with a ladder stitch or whip stitch, keeping your stitches small and hidden in the fold.
- A 2¼-inch-wide binding strip is the standard size and works for most quilts; cut enough strips to go around your quilt's perimeter plus 10 to 12 inches for overlap and seams.
Cut and prepare your binding strips
Start by cutting strips from your binding fabric. Use a rotary cutter, ruler, and self-healing mat to cut strips that are 2¼ inches wide and run across the width of your fabric (from selvage to selvage). You need enough strips to go around your quilt's perimeter plus 10 to 12 inches extra for seams and overlap. For a 60-inch by 80-inch quilt, that means cutting strips totaling about 300 inches, or roughly 12 strips at 42 inches each.
Lay two strips right sides together at a 45-degree angle so the corners overlap slightly. Draw a diagonal line across the overlap and sew along that line. Trim the excess fabric ¼ inch from the seam and press the seam open. Repeat until all your strips are joined into one long piece. Press the entire strip in half lengthwise, wrong sides together. This fold is what you will wrap around the edge of the quilt.
Sew the binding to the front of the quilt
Lay your quilt flat with the front facing up. Align the raw edges of the binding strip with the raw edges of the quilt. Start sewing about 6 inches from a corner, using a ¼-inch seam allowance. Sew in a straight line along one side of the quilt.
When you reach a corner, stop sewing ¼ inch before the corner point. Backstitch, remove the quilt from the machine, and fold the binding up at a 45-degree angle, then fold it back down so it lies flat along the next side of the quilt. The fold creates a neat 45-degree angle at the corner. Resume sewing ¼ inch from the edge of the quilt on the next side. Repeat this corner fold at each corner.
When you reach the starting point, overlap the binding ends by about 2 inches. Trim both ends at a 45-degree angle so they overlap neatly, then sew them together with a diagonal seam the same way you joined the strips. Finish sewing the binding to the quilt, closing the gap where you started.
Fold the binding to the back and pin it in place
Fold the binding over the edge of the quilt to the back side. The fold should lie just past the line of stitching you just made. Pin the binding in place as you go, working your way around the quilt. At each corner, fold the binding so it forms a neat 45-degree angle on the back. The corner should look like a small triangle of folded fabric.
Take your time pinning. Smooth out any wrinkles or bunching as you pin, especially at the corners. A quilt with a smooth, flat binding looks finished and professional. A quilt with lumpy or twisted binding looks rushed.
Hand-stitch the binding down with a ladder stitch
Thread a needle with thread that matches your binding fabric. Use a ladder stitch (also called a whip stitch) to close the binding. Bring the needle up through the fold of the binding, then insert it directly across into the quilt fabric, catching just a few threads of the quilt top. Slide the needle inside the fold of the binding for about ¼ inch, then bring it back out through the fold and into the quilt again. The thread should be hidden inside the fold, and your stitches should be small and close together — about ⅛ inch apart.
Work your way around the entire quilt. At each corner, fold the binding so the corner sits flat and stitch through all the layers of the fold to find it. Your stitches will not show from the front of the quilt if you keep them in the fold and keep them small.
This step takes patience. A lap quilt might take 2 to 3 hours to bind by hand. A queen-sized quilt can take 6 to 8 hours. Many quilters listen to music or podcasts while they stitch.
Machine-stitching the binding as an alternative
If hand-stitching is not for you, you can stitch the binding down by machine. After you fold the binding to the back of the quilt and pin it, use a walking foot and thread that matches your binding. Stitch very close to the inner fold of the binding, catching the binding and the quilt backing in one line of stitching. The stitching will show on the back of the quilt but not on the front.
Machine-stitching is faster — usually 30 to 45 minutes for a lap quilt — but it is less flexible at the corners. You have to stop and pivot carefully at each corner to keep the stitching line straight. Many quilters use machine-stitching on the front and hand-stitching on the back for a compromise between speed and appearance.
Trim and press your finished binding
Once you have stitched the binding all the way around, trim any loose threads and give the binding a final press with an iron. Press from the back of the quilt first, then flip it over and press the front. The heat and steam will set the stitches and flatten the binding so it lies smooth against the edge.
Check the corners and edges for any spots where the binding is loose or bunched. If you find any, add a few extra stitches by hand to find them. A well-finished binding should feel firm and lie flat all the way around the quilt.
Frequently Asked Questions
What size should my binding strips be?
The standard size is 2¼ inches wide. This gives you enough fabric to wrap around the quilt edge with a ¼-inch seam allowance on the front and still have fabric left over to fold to the back and stitch down. If you are using a very thick batting, you might cut strips 2½ inches wide instead.
Can I use pre-made binding instead of cutting my own?
Yes. Pre-made binding comes folded and ready to sew. It costs more than cutting your own but saves time. The process is the same: sew it to the front with a ¼-inch seam allowance, fold it to the back, and hand-stitch it down. Pre-made binding is usually 2¼ inches wide when unfolded.
What thread should I use for binding?
Use thread that matches your binding fabric. If your binding is a print or a color that is hard to match, use a neutral thread like tan or gray that blends in. For hand-stitching, use a single strand of thread. For machine-stitching, use regular quilting thread.
How do I handle binding on a quilt with curved edges?
Curved edges are harder to bind neatly because the binding does not fold flat at the curves. Many quilters trim curved quilts to straight edges before binding. If you want to keep the curves, use a narrower binding strip (2 inches instead of 2¼ inches) and take smaller stitches at the curves so the binding folds smoothly.
What if my binding puckers or bunches on the back?
Puckering usually means the binding was sewn too tightly to the front of the quilt. When you fold it to the back, there is not enough fabric to lie flat. To fix it, remove the stitching on the back, loosen the binding slightly, and re-stitch it. If the binding is already sewn to the front, you can add a few extra hand-stitches on the back to pull the binding smooth.
