Single vs double-fold binding
Most quilts use double-fold binding (also called French binding): strips are folded in half lengthwise before attaching. This creates a durable two-layer edge. The strip width is usually 2.25"–2.5" for double-fold. Single-fold binding uses narrower strips (about 1.25") and is less common today.
Mitering corners
To miter corners, stop sewing 1/4" from each corner and backstitch. Fold the binding up at 45°, then fold back down flush with the next side and continue sewing. This creates clean, flat mitered corners. Press each corner flat before hand-stitching the binding to the back.
Joining strips on the bias
Join binding strips end-to-end with a diagonal (bias) seam to reduce bulk. Place two strips right-angle to each other, right sides together, draw a diagonal line from corner to corner, sew on the line, trim leaving 1/4" seam, press open.
