How to Bind a Quilt

Binding is the final step that finishes the raw edges of your quilt. With a little math and a few seams, you can get a clean, durable edge every time.

Step 1: Calculate the binding

Binding length is the quilt perimeter plus about 12 inches for the diagonal joins and corner miters. Use the binding calculator to get the exact number of strips and yardage for your quilt size.

Step 2: Cut and join the strips

Cut strips 2.25 inches wide across the width of the fabric. Join them with diagonal seams: place two strips right sides together at right angles, sew from corner to corner, trim to 1/4 inch and press the seam open. Continue until the strip is long enough.

Step 3: Prepare the binding

Fold the strip in half lengthwise, wrong sides together, and press. The fold becomes the edge of the finished binding.

Step 4: Sew to the front

Starting mid-way down one side, align the raw edges of the binding with the raw edge of the quilt and sew with a 1/4-inch seam. Stop 1/4 inch before each corner.

Step 5: Miter the corners

At each corner, fold the binding up and away from the quilt, then fold it back down along the next side. The fold creates the miter. Sew the next side the same way.

Step 6: Finish the final join

Stop about 12 inches from where you started, overlap the ends, trim to fit, and join them with a diagonal seam before sewing the last section. This is where the extra 12 inches comes in.

Step 7: Fold and stitch the back

Fold the binding over the raw edge to the back of the quilt, covering the seam line. Hand stitch with a blind stitch, or machine stitch close to the folded edge from the front. Press for a crisp finish.

Common mistakes to avoid

Cutting strips too short — always calculate with the joining allowance, never the bare perimeter.

Seams that land at corners — start your binding on a straight side, not at a corner.

Pulling the binding tight — sew it on gently so the edge lies flat instead of rippling.
