When using the raw fabric strips cut according to the correct width, this attachment will produce the same effect as sewing double-fold 1/4 inch pre-folded bias tape. All you have to do is slip your raw bias strips into the outer slot of the binder and the attachment will fold, crease and stitch the bias to your garment - all in one motion!
