baby lock Single Fold Bias Binder 40mm

The baby lock single fold bias binder 40mm allows you to create wide, beautifully finished single‑fold bindings from fabric strips in one smooth, efficient step. Designed for use with coverstitch and combination machines, this attachment folds a 40mm wide strip of fabric into a clean, single‑fold binding and applies it directly to your project edge with perfect alignment.

According to baby lock, the precisely engineered guide channel folds the fabric evenly as it feeds through, ensuring a consistent finished width and crisp edges. The wider binding width makes this attachment ideal for home décor, blankets, ponchos, outerwear, knit garments, children’s clothing, aprons and decorative edge finishes where a broader, more pronounced binding is desired.

The binder mounts securely to the machine’s attachment base, keeping the fabric feeding straight and preventing twisting or uneven folding. Whether you're binding thicker fabrics or adding bold contrast trims, the 40mm single fold binder delivers accuracy, speed and a polished, ready‑to‑wear result.

Compatible with baby lock coverlock and coverstitch models, this binder is an essential tool for sewists who want wide, professional‑looking bindings with minimal effort.
