Machine binding is faster than hand sewing and holds up well if you use the right tension and needle
Machine binding works in two stages: you sew the binding strip to the front of the quilt with a walking foot, then fold it to the back and stitch it down by machine or by hand. The machine method is quicker than hand sewing the back, though some quilters hand-stitch the back anyway because it gives a softer finish and hides the stitches better. If you use a walking foot and keep your tension even, machine binding is durable and looks professional.
The key difference from hand binding is that your machine stitches are visible on the back of the quilt, so you need to plan for that. Some quilters use thread that matches the binding; others use thread that matches the quilt back. Either way, the stitches will show, so accept that before you start.
Key Takeaways
- A walking foot prevents the layers from shifting while you sew the binding to the front of the quilt.
- Sew the binding to the front first with a 1/4-inch seam, then fold it to the back and stitch it down by machine or hand.
- Mitering the corners by folding the binding at 45 degrees before you sew keeps the corners neat and flat.
- Machine stitching on the back is visible, so choose thread color that either matches the binding or the quilt back.
Prepare your binding strips and quilt edges
Cut your binding strips 2.5 inches wide and sew them end to end into one long strip. Press the strip in half lengthwise, wrong sides together, so you have a folded strip about 1.25 inches wide. This fold is what wraps around the edge of the quilt.
Trim your quilt to its finished size and square up the corners so they are true 90-degree angles. Uneven corners make binding difficult. Press the quilt flat, especially the edges, because wrinkles will show under the binding.
Attach the binding to the front with a walking foot
Install a walking foot on your machine. This foot feeds all the layers evenly and prevents the top layer from creeping ahead of the bottom layers. Use a 1/4-inch seam allowance, which is standard for quilting.
Start on a straight side, not at a corner. Align the raw edges of the binding with the raw edge of the quilt. Leave a 6-inch tail of binding unsewn at the start. Sew along the edge, keeping the 1/4-inch seam straight and even. Stop 1/4 inch before you reach the corner and backstitch.
At each corner, fold the binding up at a 45-degree angle, then fold it back down along the next side so the fold sits at the corner. This creates a miter. Sew down the next side the same way. Repeat at all four corners.
When you reach the starting point, overlap the binding tails by about 1 inch and trim them so they overlap exactly. Open the folds, sew the two tails together at a 45-degree angle, trim the seam to 1/4 inch, and press it open. Fold the binding back in half and sew the last few inches to close the gap.
Fold the binding to the back and stitch it down
Fold the binding to the back of the quilt so the fold covers the line of stitching you just made. Press it flat as you go around. The binding should sit evenly on the back, with no gaps between the fold and the stitching line.
At the corners, the miter you folded on the front will automatically create a miter on the back. Fold the corner so the two sides of binding meet at a 45-degree angle and lie flat.
Machine stitch the binding down on the back
Use a walking foot again for this step. Sew from the back of the quilt, stitching as close as you can to the fold of the binding without catching the fold itself. Your stitches will sit just inside the binding, on the quilt back. This line of stitching will be visible, so keep it straight and even.
Sew all the way around, including the mitered corners. At the corners, sew straight across the miter without pivoting, so the stitches go through all the layers and lock the miter in place.
Use thread that matches either the binding or the quilt back, depending on what you want to see. If your binding is a contrasting color, matching thread to the quilt back makes the stitches less obvious.
Trim and press the finished binding
Once you have stitched all the way around, trim any loose threads. Press the binding from the back with a hot iron and a pressing cloth to set the stitches and flatten the binding against the edge.
Check that the binding sits evenly on both the front and back. If any part is loose, you can hand-stitch it down with a ladder stitch, or run a second line of machine stitching if you prefer.
Hand-stitch the back instead if you prefer a softer finish
Some quilters fold the binding to the back and hand-stitch it down with a ladder stitch instead of using the machine. This takes longer but creates a softer edge and hides the stitches completely. The binding sits the same way; you just use a needle and thread instead of the sewing machine.
If you choose this route, sew the binding to the front by machine as described above, then fold it to the back and hand-stitch. Use thread that matches the binding so the stitches blend in.
Frequently Asked Questions
What happens if my corners are not square?
Uneven corners make the binding sit crooked and create puckers. Before you attach binding, measure all four corners and trim the quilt so each corner is a true 90-degree angle. A square ruler makes this easier. If your corners are already bound and crooked, you can trim them after binding is complete, but it is harder to keep the binding straight.
Can I use a regular presser foot instead of a walking foot?
You can, but a walking foot is worth the investment. Without it, the top layer of the quilt often creeps ahead of the bottom layers, creating puckers and uneven seams. A walking foot costs between $25 and $60 and works on most machines. If you do not have one, sew slowly and stop frequently to check that all layers are feeding evenly.
What if the binding twists or puckers while I sew?
Puckers usually mean the layers are not feeding evenly, which a walking foot prevents. If you see puckers forming, stop and gently pull the quilt back to release the tension, then continue. Make sure the binding is folded straight and the raw edges are aligned with the quilt edge before you sew.
Should I use the same thread color on the front and back?
No. The front stitches are hidden under the binding fold, so thread color does not matter there. On the back, use thread that matches either the binding or the quilt back, depending on what you want to see. Matching the quilt back makes the stitches less obvious.
Can I machine-stitch the binding on the back if I hand-stitched the front?
Yes, though it is not common. Most quilters either machine-stitch both sides or hand-stitch both sides. If you hand-stitch the front, machine-stitching the back will create a visible line of stitches that does not match the hand-stitched front. It is possible, but the finish will look uneven.
