-This clever device allows you to finish an edge with bias binding. Not only can you use commercial bias binding, but also binding which you cut yourself. In one operation both edges of the binding are stitched neatly and evenly in place. Pinning and basting are eliminated. Raw edges disappear forever. The stitching is even and close to the folded edge of the binding.
-Slotted binder 1/4".
-Fits Singer models 401a, 403a, 500a, 503a, 600 series, 700 series
